应用在调试模式下流畅运行，但在发布时无法打开应用 apk flutter

Question

我在清单中使用了权限但没有用

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

我还使用了 flutter build apk --release --no-shrink 不起作用，我也使用了 flutter clean not wokred，我将 gradle 4.1.0 更改为 3.5.0 不起作用，我将 distrubution gradle 6.7all 更改为 6.5。 1都没有用

我使用的软件包

  http:
  sqfentity:
  flutter_riverpod:
  shared_preferences: ^2.0.6

我用过

import 'package:flutter_riverpod/flutter_riverpod.dart';

import 'pages/signup_page.dart';

void main() {
  runApp(ProviderScope(child: MyApp()));
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Container(),
    );
  }
}

我添加了 multiDexEnabled、shrinkResources 和 minifyEnabled 并解决了

android {
    compileSdkVersion 30

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.assignmenet"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        ndkVersion "22.1.7171670"
        multiDexEnabled true
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            shrinkResources false
            minifyEnabled false
        }
    }
}
