After my app failed on iOS 17, I had to do a lot of upgrading, including buying a new Macbook, just so I can do a build for iOS 17. It turned out that the TextFormField in Flutter didn’t work with Autocorrect in iOS 17.
So, after upgrading Macbook, XCode and Android Studio, I had a lot of packages to update as well (my app was only 2 years old). I am now using Android Studio Giraffe. Getting my app to work again because of all the updates to the packages took quite a while, but I have it all working now.
I normally develop on my Windows computer, so I copied all my changes to Windows, upgraded Android Studio to Giraffe, ran Flutter Pub Upgrade to get latest version of Flutter and Dart and attempted a build, but this is where I have stalled.
I am getting error…

I am a bit stuck, and there is very little I can find to resolve this.

I am not writing for Windows, so the reason for VS2019 is not required. I have Java version 8 installed.
When I try to upgrade Gradle using the AGP Ugrade Assistant… nothing happens.
I don’t know where else to turn to find out how to get beyond this.

Currently, pdfx package has a problem due to flutter upgrading to version 3.16 as mentioned in this issue https://github.com/ScerIO/packages.flutter/issues/448
There is a temporary way to fix it by changing the pdfx package inside your pubspec.yaml
from
pdfx: ^2.4.0
to
I solved this issue, by updating the versions of the packages that I have used by running the following command:
flutter pub upgrade;
There is high possibility that some versions might cause conflicts and won’t upgrade in that case after running the above command you can run the following command:
flutter pub upgrade –major-versions;
and now you can generate the builds or the app bundle. This is how I solved this issue.
