While I agree that the bug fixing capabilities of the flutter team could be improved, it‘s still reasonable to assume that they‘re primarily caring about Google‘s issues - given Google pays the party.
Still, you comparison isn‘t really a good fit IMHO because it seems you’re „just“ wrapping html content into the native ecosystem, which defeats somehow the purpose of actual native apps.
And even if you‘ll only target iOS I‘d say Flutter is still a more pleasant and more productive tech to use compared to f.e. SwiftUI - of course this only applies for actual native code.
Still interesting to read, thx for the article.
I might modify the title though since I wouldn’t consider a html wrapper a native app you‘re migrating to flutter.
