Flutter app freeze in build release, work properly in debug, androidX?
问题 final update: now everything works; while before I was not adding internet permission and the app worked perfectly (contacting API and everything), since the update I have to explicitly modify the manifest. Easy fix actually: manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.xxx.xxx"> <uses-permission android:name="android.permission.INTERNET"/> <application android:name="io.flutter.app.FlutterApplication" android:label="xxx" android:icon="@mipmap/ic_launcher">
