Video Player

Video buffering when trying to play it flutter dart

Issue

I am trying to create a dog photo/video generator app using Flutter and Dart. It basically sends a get request to a website called random.Dog to get a url to show on my app. Sometimes the url is a video and sometimes it is a img. When it is a video my app just buffers and this console message keeps on coming:

And my video doenst show up on my emulator. What seems to be the problem and how do I fix it? My minimal code:

import 'package:better_player/better_player.dart';


void main() => runApp(MaterialApp(home: RandomDog()));

class RandomDog extends StatefulWidget {
  @override
  _RandomDogState createState() => _RandomDogState();
}

class _RandomDogState extends State<RandomDog> {
  var headers = {'Content-Type': 'application/json'};
  var body = {};
  var video = false;
  var img = false;
  var message;
  var loading = true;
  var _controller;

  @override
  void initState() {
    getDog();
    super.initState();
  }

  getDog() async {
    loading=true;
    var response = await http.get(Uri.https('random.dog', '/woof.json'));
    print(response.body);
    message = jsonDecode(response.body);
    if (message['url'].contains('gif') || message['url'].contains('png') ||
        message['url'].contains('jpg') || message['url'].contains('jpeg')) {
      video = false;
      img = true;
    } else {
      video = true;
      img = false;
    }
    loading = false;
    setState(() {

    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        . . .
      body: Center(
        child: loading == true ? CircularProgressIndicator() : Column(
          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: CrossAxisAlignment.center,
          children: [
            Visibility(visible: img,
                child: Image.network(message['url'], fit: BoxFit.scaleDown,)),
            // Visibility(visible: video,child: VideoApp(url:message['url'])),
            video == true? CircularProgressIndicator() :
                Visibility(visible: video, child: BetterPlayer.network(message['url'],betterPlayerConfiguration: BetterPlayerConfiguration(autoPlay: true),)), //Chewie(controller: _controller,)
            
            OutlinedButton(onPressed: () async {
              getDog();
            }, child: Text('GENERATE')),
          ],
        ),
      ),
    );
  }
}

Solution

Hope this solution work for you, Try to initialize your betterPlayer in your function getDog() by using :

BetterPlayerController _betterPlayerController; //declare first

 BetterPlayerDataSource betterPlayerDataSource = BetterPlayerDataSource(
    BetterPlayerDataSourceType.network,
    "message[url]");
_betterPlayerController = BetterPlayerController(
    BetterPlayerConfiguration(),
    betterPlayerDataSource: betterPlayerDataSource);

after that in your widget after CircularProgressIndicator you add this :

BetterPlayer(
        controller: _betterPlayerController,  ),
