> your team needs to be more transparent.
Unfortunately most of the lack of transparency is not under the Flutter team's control, but I'll see what I can do.
> How is Flutter funded?
A number of companies (Google, Bytedance, and Canonical are three that I know have publicly stated so; there are others but it's up to them to make such statements) employ people to work on Flutter. Hardware costs (CI, source control, bug database, etc) are paid for by Google and Microsoft.
These companies don't typically share more detailed information about how they account for this funding or how much they pay exactly; it's considered proprietary, and often there are legal implications to making detailed statements about this kind of thing.
> It was said a few years ago the budget came from internal projects like ads, fuchsia, pay, and stadia
(I'm assuming you are referring to Google's portion of the funding.) That's not really how Google accounts for things internally. Broadly speaking, the more usage (internal and external) that a product gets, and the more revenue can be assigned to a product, the more Google is likely to fund it. In the case of Flutter, Google is apparently quite happy and has been increasing funding over time as a result, as have other companies (as you can tell by looking at the number of people employed to work on it).
> does stadia being killed effect the Flutter budget?
No, that's not how things work at Google. (I assume you mean Google's investment in Flutter when you say "Flutter budget". Flutter itself, as an open source project, doesn't have a budget currently. Maybe one day we'll have a foundation but right now the additional management overhead doesn't seem worth it.)
> There was an implication at that time that if they all died or left Flutter then it would be killed via budget cuts, is that true?
I think when there were far fewer apps using Flutter, and fewer other companies using and contributing to Flutter, that if Google had stopped using it internally, after a while, it would have become difficult to justify continued investment (since in that scenario, very few people are using it at all, so what's in it for Google? Google isn't a charity). However, at this point Flutter is used a great deal outside Google, as Tim discusses in his comment above, and even if Google itself were to stop using it (which seems highly unlikely) there would still be plenty of justification to continue funding it as a developer product (many of Google's APIs and developer products aren't used internally at all).
That said, this is not intended to be a forward-looking statement (https://en.wikipedia.org/wiki/Forward-looking_statement). If you want to ask Google about its future funding plans I suspect the best place to do so is a stockholders conference call.
> Why is Flutter not being adopted by Google for more outward facing apps?
With some exceptions that involve negotiations with the relevant teams, Google doesn't generally talk about what technologies it uses for its own applications. Tim listed quite a few apps whose teams have agreed to publicly state they use Flutter, though. I'm not sure what else to tell you. It's not like Google is making new apps all the time, and rewriting an app in Flutter only makes sense if the app's team benefits from the rewrite in some way.
> Is it seen internally as at risk of abandonment?
No. (But then, why would you take my word for it.)
> "600,000 apps in the Play Store alone", how many of these are commercial vs hobby projects
I don't think this is an axis along which apps are categorized, so I've no idea how to answer that. (What is a "hobby project"? Does it count as commercial if someone charges for their hobby?)
> does Google really care about these if enterprise adoption is minimal?
Yes? We care about all apps.
> Delving into game dev when iOS is not polished seemed like a decision made because there was a need to show potential value via expansion upward in the org, I was concerned this was a hail mary when announced, and with Stadia now gone the timing seems more suspect.
I'm not sure what you're suggesting here. Our work on iOS is entirely orthogonal to the work on the Casual Games Toolkit, it's not like the people who worked on one could work on the other. The Casual Games Toolkit is intended to help people who are interested in writing games with Flutter but don't know where to start; we regularly do surveys of our developer base and this was an area that people indicated an interest in. I'm not really sure what the supposed link to Stadia would even be. Work on iOS continues, and we have significantly grown the team there in the past year.
> "It has a developer base of several million", how many of these are again hobby users
We occasionally post the data from our quarterly surveys to our blog on Medium, the latest post I could find that separates the data by "what is your primary purpose" was the Q3 2021 survey's report and it had this graph: https://miro.medium.com/max/1400/0*_GNHkk5TLOI7wQYc
Looks like it's <50% are "hobby" users and the number is shrinking. That said, we explicitly want to be a project that people use to learn programming, providing a seamless path from "learning" to "hobby" to "professional" so I would hope this number never gets very low.
> how many use it weekly / monthly?
That's very hard to say for a variety of reasons (e.g. many people turn off analytics, analytics are extremely unreliable in general, many people use Flutter via means that wouldn't trigger our analytics in the first place, etc) but my understanding is that as best we can tell, Flutter has well over 500,000 MAUs. I don't think we track weekly numbers.

I've no idea how to measure that.
> Your team was asked approximately this question by a MSFT employee looking at publishing info on cross platform framework adoption vs native and could not get a straight answer I was told.
I mean, there's some questions we just don't have the answer to. I'm not sure what to tell you. We do share quite a lot of our data, e.g. from the quarterly surveys, as noted above; for most of your answers the numbers I just gave you can be found by Googling.
I would personally love to share more (e.g. I'd love for the analytics to be public) but there are significant privacy constraints around this. Even within the team, most people don't have access to the analytics data, and we're actually making an effort to limit that even more as part of our extensive efforts around tightening security.
I hope one day we can anonymize and aggregate the data to a level that satisfies Google's privacy team and then we'll be able to share the numbers in real time, but that won't be for some time (if ever, this stuff is hard).
> Multiple Flutter related posts by agencies and evangelists point to a google trends page or GH stars saying Flutter is blowing up in popularity compared to other frameworks
I would point to things like numbers of users or apps rather than vanity metrics like GitHub stars, but there we go.
> but when you start looking at core packages searched for and starred for each framework the Flutter trend reverses, is this because the words Flutter and Dart are too common and in actuality the popularity is not what is being projected in trends?
I would posit that it is because Google Trends data is a terrible way to measure popularity of an SDK.
> Is this because DevRels directly ask people to star the core project?
GitHub stars are purely a vanity metric. I would ignore them.
> I ask Flutter GDE's these questions and they come off like they can't be trusted to be honest on these topics for fear of losing status.
Feel free to tell them to reach out to me if they ever have a question about what they can or can't say.
> I have also heard a certain outspoken Flutter GDE mention on stream other frameworks have much larger communities, how can this jive with these purported trends?
Flutter is big and growing, but there are plenty of much bigger SDKs, certainly. I don't think that's a big secret. :-)
> It seems as though the community size and growth of Flutter is projected to be greater than it is, that's subjectively how it feels as a dev as well I will note as someone who is using packages / repos, and that is worrisome.
There are plenty of SDKs with much smaller communities that are very healthy and have been around for decades. I think it's reasonable to be concerned about ecosystem health, but I must say that personally I am quite happy with Flutter's ecosystem and community size and growth.
> I worry that the first time we hear solid numbers will be in a blog post about the Flutter project ending with an explanation that low enterprise adoption and direct or indirect revenue could not support the scale of this ambitious a project.
Well good news, the numbers you asked for have largely already been discussed publicly, so you need not have that specific worry.
> It would be great to hear some hard facts that give people confidence in adoption and that Flutter has long term backing higher in the company. If this is not the case, honesty would be nice as well.
I can't promise long-term backing from Google, because I'm not the CEO and ultimately it has to be his call. I can point to all the reasons Tim gave above for why there's no reason to expect Google to abandon Flutter any time soon, and I can point to the numbers I gave above as the "hard facts" you are looking for, or at least the closest things to them that one can have. Unfortunately with squishy things such as ecosystem size and how people use products and so on there is so much noise in the data, such big error bars, that anyone giving you precise numbers is selling you snake oil.
> @a14n seems to have tailed off on his work on Flutter quite a bit, which worries me if he is the core example of users who would pick this up in an OSS abandonment situation.
I think Tim just pointed to a14n because he's contributed so much over the years. No one person could take over the project and I certainly wouldn't put that on a14n's shoulders!! You can look at our GitHub and Discord activity to see how the project is doing in terms of non-Google contributors.
> Even now it feels as though if major OSS package maintainers like Remi Rousselet walked away the community would be hit hard.
We are a long way past there being any single person who is keeping the project afloat.
> I can't imagine the project continuing without Google, especially with Dart needing the same treatment if Flutter was killed. Dart issues with notes saying the team lacks bandwidth exist now, I just can't see it working even with some other companies interested, Flutter/Dart need full enterprise backing at this stage.
You never know. FreePascal is an example I love to point to; it's an open source project with minimal (if any) corporate/enterprise funding and yet they have been delivering reliably for decades now. I don't see why a dedicated team couldn't pick up Dart in the same way, if the interest was there.
> BUT, it still has the biggest complaint I hear about Flutter apps on iOS, feel.
The biggest complaint we hear is definitely jank, FWIW. :-)
> On iOS is does not feel native, the scrolling and gestures feel off.
If you have specific reproducible cases of this, please file bugs with test cases demonstrating it. The more concrete and specific you can be (e.g. high speed video showing the difference) the better.
We actually have built tools to verify that we are matching iOS physics to the pixel, so if there are cases where we're not, we would love to learn about them and fix them. (Unfortunately until recently we were mostly focused on lower-level issues on iOS, like performance and plugins, and have not had as much time to spend on widgets and physics. That's changing, though.)
> This is part of what I was referring to regarding ignoring polish on iOS in favor of expansion earlier, iOS still feels second class on Flutter.
We've made huge strides here in the past year, but yeah, we still have work to do.
> My final thought is the same as my first, be more transparent, show the community with tangible honest numbers and backing Flutter is not in jeopardy, otherwise the track record (and imho vague mushy pumped up stats) makes it appear it is.
As far as I can tell, we've been transparent, with most of the numbers you say you'd like us to share being numbers we have in fact shared already. The numbers are not made up, but yes, they are mushy. If you have any idea how to get less mushy numbers, join our Discord, help us out (the link to the Discord is in the contributor docs on GitHub).

On the budget / funding side I understand not all details can be shared, I think the general gist is just the broad question of what can effect flutter funding. It sounds like Stadia shut down won't, but I see that question was also raised on Reddit, so clarity on that was appreciated beyond myself I am sure, and any more would be appreciated as well.
On internal apps, I know Flutter is being used, this sort of leaks into PRs, comments, etc, but I think the question I was getting at is if that has enough value to google. On the outward facing apps this is definitely a matter of perception, I don't think I need to expand there.
The hobby projects, I think this is hard to define but is a classic you know it when you see it. The result of a single Udemy course, something that serves 0 to few users (most of whom are the devs friends), something not actively being developed, something where the code base is quite small, etc. Projects done and published for the sake of learning more than their use to others is likely where I would draw the line. I think there is another line at profitable / paid dev, but I would say the lesser line is appropriate. I think the wider question is how many people are getting enough value out of Flutter that it truly translates into value for Google that is worth sustaining, definitely not an easy question to answer.
> I'm not sure what you're suggesting here. Our work on iOS is entirely orthogonal to the work on the Casual Games Toolkit, it's not like the people who worked on one could work on the other.
This is still hard for me to swallow. Codegen for json deserialization, data types, general slowdown in the analysis server at scale, the list feels long, I would have to dive into the current issues to get them all. But coming from other languages / frameworks there is an incompleteness that feels more important to address than games no matter what a survey says. Saying they are orthogonal is denying resources/funds could be used differently for different goals. The Stadia link was simply it seems growing Flutter user base has a priority over polish, and with an internal app shutting down it seemed growth could itself grow in importance over polish.
> <50% are "hobby" > 500,000 MAUs
Thank you! This!! This gives some idea of how many devs are truly working on Flutter worldwide. These numbers make much more sense to me and what I see!"It has a developer base of several million", I felt like this was gaslighting me as I could not see where all these devs existed, how were stackoverflow issues that seemed like they should be semi-common with 0 to 1 replies!? This did not jive with millions of dev, even a small percent working at enterprise scale, and did not fit with my experience working on other frameworks that claim similar scales.

Combine the use of these two stats being heavily pushed in blogs etc with the, "It has a developer base of several million", quote, mix in first hand observations that they feel off, and the feeling the team is hiding something starts to manifest. Especially when blog posts turn these stats into proof through twisting that Flutter is for lack of a better term, "the biggest". Thank you for noting these are vanity numbers, imho pushing them does a disservice. I will also submit that at 5 years old continuing to push the narrative that Flutter is "new" and the nearest competitor only has any gains do that that gap starts to get some side eyes.
> We are a long way past there being any single person who is keeping the project afloat.
Agreed, but still it feels like there are a few big hitters, it does not go unnoticed where he works and I am guessing is sorta paid by proxy by Google.
> I don't see why a dedicated team couldn't pick up Dart in the same way, if the interest was there.
Agreed on Dart, I think Flutter is another matter though.
> The biggest complaint we hear is definitely jank, FWIW. :-)

These feel tied together, I mean this in a honest way and not to offend the team, but does anyone on the team use iOS full time and run Flutter apps on device in prod regularly (just cruise ebay motors?)? I talk to other iOS users and this is a well known issue, scroll acceleration is off (scroll fast and it's WAY off), there is an issue already posted for Flutter with scroll being a full frame behind native so the location / perceptions feels off at first touch, and pull to refresh is a bit janky at times. "We actually have built tools to verify that we are matching iOS physics to the pixel" I mean no offense, but is something code wise wrong in the tooling? As a full time iOS user it's VERY obvious, you feel it and see it, my friend literally deleted an app due to it after using it for seconds, it's not just a vague complaint, it's highly perceivable.
> We've made huge strides here in the past year, but yeah, we still have work to do.
TY
> As far as I can tell, we've been transparent, with most of the numbers you say you'd like us to share being numbers we have in fact shared already.
I have gotten more info from this post than anything else I have read on the state of Flutter, appreciate it.
