我以前有过这个错误

尝试添加

         multiDexEnabled true

到android/app/build.gradle

defaultConfig {
     
        applicationId "com.your_app.your_app"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
         //Add this Line
        multiDexEnabled true
    }
