ajoutez ce qui suit à vos règles ProGuard

-ignorewarnings

-keep class * {
    public private *;
}

et reconstruisez votre projet.

A.N.T

essayez ceci à votre proguard-rules.pro

-ignorewarnings
-keep class * {
    public private *;
}

Seulement -ignorewarnings cette ligne a résolu mon problème.

Ajoutez également la ligne suivante à <ProjectRoot>/Android/gradle.properties à Obfuscating Dart Code:

extra-gen-snapshot-options=--obfuscate

Pour référence

Aussi, si vous utilisez Firebase Auth , ajoutez-le au fichier proguard-rules.pro:

-keep class com.google.firebase.** { *; }

Partage de mon fichier /Android/app/proguard-rules.pro

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }
-ignorewarnings

J'espère que quelqu'un va aider cela

Fermez le projet et Android Studio. Ouvrez à nouveau le projet, reconstruisez le projet. Et ensuite, vous pouvez essayer de générer l'APK. Cela a fonctionné pour moi. Bien câblé!

Vous pouvez essayer ce keep class com.xyz.** { *; } -dontwarn com.xyz.**
