I have also face the same issue in Android 11.

Below workaround working for me.

On your app-level build.gradle add this to your buildTypes > release section

shrinkResources false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

Along with the build.gradle file create a proguard-rules.pro file if not exist and add:

-keep class io.flutter.plugin.editing.** { *; }

run in cmd or terminal and accept all licenses and again run a project

flutter doctor --android-licenses
