here are my gradle files

buildscript {

CodePudding user response：

1. Check your Gradle version and make sure it is up to date.

2. Make sure you have the latest version of the Android SDK installed.

3. Check your Flutter dependencies and make sure they are all up to date.

4. Try running flutter clean and then rebuilding the project.

5. If none of these steps work, try deleting the .gradle folder in your project directory and then rebuilding the project again.

CodePudding user response：

The error code 1151 in Gradle in Flutter typically occurs when a conflict arises between different versions of the same library. This can happen when multiple packages depend on different versions of the same library. To resolve this error, you can try the following steps:

Run flutter clean command in terminal Update Gradle to the latest version by updating the Gradle version in the gradle/wrapper/gradle-wrapper.properties file. Manually resolve the dependency conflict by specifying the correct version of the library in your pubspec.yaml file. If all else fails, try removing the conflicting library and re-adding it. If none of the above steps solve the problem, it's best to consult the library's documentation or seek help from the library's support forums.
