问题 I've been trying to use the Android NDK's AssetManager class in my Flutter app, that works with Google Oboe, to access to audio files. Following this example in the Oboe repository, I learned that they obtain the AssetManager from Java like this: JNIEXPORT void JNICALL Java_com_google_oboe_sample_rhythmgame_MainActivity_native_1onStart(JNIEnv *env, jobject instance, jobject jAssetManager) { AAssetManager *assetManager = AAssetManager_fromJava(env, jAssetManager); if (assetManager == nullptr)

问题 ListTile OnTap is working when I use ListView. But when i use ListWheelScrollView it doesn't work. I mean it doesn't get tapped. The view changes. But i can't seem to tap it. I looked for the solution in a lot of places and links but still couldn't find the solutions. These are the code I did. @override Widget build(BuildContext context) { return new ListWheelScrollView( physics:FixedExtentScrollPhysics(), children: getPostList(), itemExtent: 100.0, ); } List<PostListItem> getPostList() {

问题 This is about Flutter Firebase Authentication plugin. I am trying to send a verification email after creating a new user, but sendEmailVerification() internally uses currentUser(). This looks like a bug to me, but just in case, I am posting a question to stackoverflow. The error is the same on Android and IOS. First two lines return FirebaseUser. The third returns null. Forth, if third is commented throws a null reference error. Thanks, Boris user = await _auth.createUserWithEmailAndPassword
