Im creating a chat using flutter firebase. I want to record audio audio when I click the "mic" icon. but I'm getting these errors in my code. message sending is already working. now I want send voice messages and store them in firebase. I refer this video for the implementation. for your reference you can find my full code files. voice recording codes are highlighted. >> methods.dart , chatRoom.dart , serach.dart. think Im placing the code incorrectly. apriciate your hep on this.
.
The method 'initState' isn't defined in a superclass of 'ChatRoom'. The method 'dispose' isn't defined in a superclass of 'ChatRoom' The method 'setState' isn't defined for the type 'ChatRoom'.

bool show = false;

final icon = isRecording ? Icons.stop: Icons.mic;
final text = isRecording? 'STOP': 'START';
final primary= isRecording? Colors.red : Colors.white;

Are you sure your ChatRoom component is a StatefulWidget?
CodePudding user response：
Since ChatRoom is a StatelessWidget, it does not have access to the initState method, since there is not state to initialize.
