Flutter Android application stopped to build after last Flutter update

Question

My new flutter version follows:

Flutter 3.13.9 • channel stable • https://github.com/flutter/flutter.git
Framework • revision d211f42860 (7 days ago) • 2023-10-25 13:42:25 -0700
Engine • revision 0545f8705d
Tools • Dart 3.1.5 • DevTools 2.25.0

After upgrade I see following build error:

ERROR:D8: com.android.tools.r8.kotlin.H
ERROR:D8: com.android.tools.r8.kotlin.H

FAILURE: Build failed with an exception.

How to bypass this bug and still build the application?

Clearing caches, removing .gradle and similar folders change nothing.

Answer 1

For me, the issue comes from adding built_value: 8.7.0 in the dependencies (either directly or indirectly), while using firebase_analytics plugin. And it will only occur if your app level(android/app/) build.gradle compileSdkversion is 34. An issue was created on flutterfire repo so lets wait for the fix.

One temporary workaround would be either

• Reduce the compileSdkversion to 33 if its set to 34
• Use older version of built_value

I didn't need to change anything else so see what works for you.

Answer 2

I have the same issue, it seems this is some kind of bug. Downgrading to

 classpath 'com.android.tools.build:gradle:7.3.0'

seems to resolve this. More info could be found here: https://github.com/firebase/flutterfire/issues/11853
