This error often arises due to conflicting definitions of classes, specifically the io.flutter.plugins.webviewflutter.BuildConfig<\/code> class, during the build process.<\/strong><\/p>\n\n\n\n

The DexArchiveMergerException<\/code> occurs when there are conflicting definitions of classes in the Dex archives. In your case, the issue is with the io.flutter.plugins.webviewflutter.BuildConfig<\/code> class, which is being defined multiple times.<\/p>\n\n\n\n

<\/h3>\n\n\n\n

Dependency Clash:<\/strong> The error suggests that there is a clash in the dependencies related to the webview_flutter<\/code> plugin, leading to duplicate class definitions.<\/p>\n\n\n\n

Build Process Issue:<\/strong> During the build process, the DexArchiveMerger is responsible for merging multiple Dex archives into a single one. The conflict arises when it encounters identical class definitions in different archives.<\/p>\n\n\n\n

How to Solve the Issue:<\/strong><\/h3>\n\n\n\n

Exclude Duplicate Dependencies:<\/strong> Check your pubspec.yaml<\/code> file for duplicate dependencies or conflicting versions. Exclude unnecessary or conflicting dependencies and ensure that you are using the correct versions.<\/p>\n\n\n\n

dependencies:\n  webview_flutter: ^latest_version\n\n<\/code><\/pre>\n\n\n\n
Clean Build:<\/strong> Run a clean build to remove any previously generated files that might be causing conflicts.<\/p>\n\n\n\n
flutter clean\nflutter pub get\n<\/code><\/pre>\n\n\n\n
Check Gradle Configuration:<\/strong> Ensure that your build.gradle<\/code> files are correctly configured. Check for any custom configurations that might be causing conflicts.<\/p>\n\n\n\n
Update Flutter and Plugins:<\/strong> Ensure that you are using the latest stable version of Flutter and update your plugins to their latest versions.<\/p>\n\n\n\n
flutter upgrade\n<\/code><\/pre>\n\n\n\n
