oodavid / flutterby Goto Github PK

I found a problem in the 002-infinite-loading-pull-to-refresh example:
When I click the "Show Posts" button, and get to the Posts page for the first time, the frames will be rendered continuously, we can check it with the performance overlay. With an emulator, I get 100% cpu load at that time.
When I scroll down to load more elements, the problem will go away.
When I go to the top, and use pull and refresh, the problem comes again.
I tried to analyze the problem with profiling, but could not find the problem.
I use flutter 1.20.3 and dart 2.9.2.

This is a very useful implementation of infinite scrolling and your videos are great, however I found that if there isn't enough data to fill the screen (i.e no need for scrolling) then the loading widget appears at the bottom and never goes away. Is there a way to fix this? This happens, for example if we choose 10 in the following line (in models.dart).

return _getExampleServerData(10).then((postsData)

Thank you for this wonderful example. However, I see a couple of things missing. Having those will give us a more complete picture.

Stream<MyUserModel> userStream => FirebaseAuth
  .instance
  .onAuthStateChanged
  .map((user) => MyUserModel.fromFirebase(user));

String documentPath = 'my/document';
Stream<MyDocumentModel> documentStream = Firestore.instance
    .document(documentPath)
    .snapshots()
    .map((snapshot) => MyDocumentModel.fromFirebase(snapshot));

Can you add code that adds MyUserModel and MyDocumentModel?

hi David, great videos thanks very much! Could you possibly add the models used by the provider example + provide a complete / working app via Github (for the provider pattern walk through) ?
