I use Flutter every day...your team needs to be more transparent. Tangible answers and numbers, "Happy developers are a prerequisite for a wide variety of other Google APIs and services", is great, but those services and APIs have a variety of other entry points not using Flutter, they don't depend on it.
How is Flutter funded? It was said a few years ago the budget came from internal projects like ads, fuchsia, pay, and stadia, does stadia being killed effect the Flutter budget? 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? Why is Flutter not being adopted by Google for more outward facing apps? Is it seen internally as at risk of abandonment?
"600,000 apps in the Play Store alone", how many of these are commercial vs hobby projects, does Google really care about these if enterprise adoption is minimal? 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.
"It has a developer base of several million", how many of these are again hobby users, how many use it weekly / monthly? Flutter has a large DevRel push, how many of these projects / users are students who just spin it up once and hit star on GH when asked and never touch it again? 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.
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, 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? Is this because DevRels directly ask people to star the core project? 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. 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?
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. 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. 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.
@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. Even now it feels as though if major OSS package maintainers like Remi Rousselet walked away the community would be hit hard. 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.
"which is using the new engine on iOS" - An aside... I downloaded the app, it seems pretty smooth, not sure the FPS but I saw minimal jank which is great. BUT, it still has the biggest complaint I hear about Flutter apps on iOS, feel. On iOS is does not feel native, the scrolling and gestures feel off. 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. I have watched a friend delete a flutter app from their phone right after installing with the reasoning "I hate when apps feel like that, it's so obnoxious", these people exist, they feel Flutter apps are second class, this sentiment will 100% drive away enterprise adoption imho. Even recently a user on the flutterdev subreddit said they were leaving Flutter behind just do to this persistent user feedback.
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.
