Я совсем новичок в Flutter и разрабатываю свое первое приложение. До сих пор это действительно язык куола, но в последнее время я столкнулся с некоторыми проблемами.

Я хочу добавить в свое приложение видеоплеер, такой как video_player или chewie. Но каждый раз, когда я это делаю, я больше не могу запускать свое приложение на своем эмуляторе Android. Он отображает это сообщение об ошибке :

Каким-то образом это отлично работает на Chrome.
После некоторых исследований я обнаружил, что это может быть связано с версией Android, но после попытки обновить обе AndroidManifest.xml и build.gradle Я еще не нашел рабочего решения.

У кого-нибудь есть решение этой проблемы ? Я был бы очень признателен за некоторую помощь

Итак, вот мое андроидное проявление :

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.onyvideoplayer">
   <application
        android:label="onyvideoplayer"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that, this theme continues
                 to determine the Window background behind the Flutter UI. -->
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <!-- Displays an Android View that continues showing the launch screen
                 Drawable until Flutter paints its first frame, then this splash
                 screen fades out. A splash screen is useful to avoid any visual
                 gap between the end of Android's launch screen and the painting of
                 Flutter's first frame. -->
            <meta-data
              android:name="io.flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>
 

и моего телосложения. :

 def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

    }
}

flutter {

Hope someone can help me on this one ! Much love !
