I'm absolutely shocked by the poor consideration from the FF team about this recent update.
If you're going to update the Flutter version, please, at least consider doing the Gradle migration yourself because, respectfully, that's what I'm paying you to do.
It's unacceptable to make this change and make it the user's problem to deal with all the incomplete migrations/upgrading incompatible dependencies and so...
I'm 5 hours deep into completing all sorts of incomplete files that you failed to update when making this upgrade, I had everything work fine for me on VS Code before the recent upgrade to Flutter version 3.19.1, now, although everything is fine on FF, when I download the code to publish the app, and try to run it on VS Code, I get a ton of errors, one at a time which is caused by a lot of absolute carelessness from you.
Please, If you want to upgrade to the latest Flutter version, make sure to migrate and update every bit of the generated code because 99% of your customers have zero experience with coding and are purchasing your product so they can save themselves all the unpleasant experience that you made me go through in the past couple of hours.
I feel betrayed... you should've known better...
I hope you take care of those issues soon.
