How To Fix Flutter AndroidX Incompatibility?

I just import webview_flutter plugin and found that the plugin has incompatible with my flutter environment. Then using Android Studio I migrate my AndroidX environment with "Migrate to AndroidX" option.

I want to use webview_flutter plugin for viewing the page. Help appreciated.

Here is the error message

Launching lib/main.dart on Andromax B26D2H in debug mode...

Thanks for your suggestion,

I've fixed it by doing these steps : 1. Try adding this line In your Project folder > android > app > build.gradle, add the following Line in

multiDexEnabled true

inside defaultConfig

2. Then upgrade gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (previously on version 3.2.1)

3. Run flutter clean and rebuild your project
