how to automatically trigger record - flutter

Question

I have a audio recording page which starts when I tap in the button and stop when i tap the button once again
import 'package:flutter_sound/flutter_sound.dart';
import 'package:permission_handler/permission_handler.dart';
class AudioWidget extends StatefulWidget {
#override
State<AudioWidget> createState() => _AudioWidgetState();
}
``class _AudioWidgetState extends State<AudioWidget> {
final FirebaseAuth _auth = FirebaseAuth.instance;
String AudioUrl = '';
final recorder = FlutterSoundRecorder();
bool isRecorderReady = false;
#override
void initState() {
super.initState();
initRecorder();
record();
}
#override
void dispose() {
recorder.closeRecorder();
super.dispose();
}
Future initRecorder() async {
final status = await Permission.microphone.request();
if (status != PermissionStatus.granted) {
throw 'Microphone permission not granted';
}
await recorder.openRecorder();
isRecorderReady = true;
recorder.setSubscriptionDuration(const Duration(milliseconds: 500));
}
Future record() async {
if (!isRecorderReady) {
return;
}
await recorder.startRecorder(toFile: 'audio');
}
Future stop() async {
if (!isRecorderReady) {
return;
}
final path = await recorder.stopRecorder();
final audioFile = File(path!);
print('Recorder audio: $audioFile');
final ref = FirebaseStorage.instance
.ref()
.child('Audio')
.child(DateTime.now().toIso8601String() + ".mp3");
await ref.putData(audioFile.readAsBytesSync());
AudioUrl = await ref.getDownloadURL();
FirebaseFirestore.instance.collection('Audio').add({
'AudioUrl': AudioUrl,
'userId': _auth.currentUser!.email,
'createdAt': DateTime.now(),
});
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text("Audio"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
StreamBuilder<RecordingDisposition>(
stream: recorder.onProgress,
builder: (context, snapshot) {
final duration = snapshot.hasData
? snapshot.data!.duration
: Duration.zero;
String twoDigits(int n) => n.toString().padLeft(2, '0');
final twoDigitMinutes =
twoDigits(duration.inMinutes.remainder(60));
final twoDigitSeconds =
twoDigits(duration.inSeconds.remainder(60));
if (twoDigitSeconds ==
FFAppState().AudioMaxDuration.toString()) {
stop();
}
return Text('$twoDigitMinutes:$twoDigitSeconds',
style: const TextStyle(
fontSize: 80,
fontWeight: FontWeight.bold,
));
}),
const SizedBox(height: 32),
ElevatedButton(
child: Icon(
recorder.isRecording ? Icons.stop : Icons.mic,
size: 80,
),
onPressed: () async {
if (recorder.isRecording) {
await stop();
context.pop();
} else {
await record();
}
setState(() {});
},
),
],
)),
),
);
}
}
how can I automatically start recording once I open the audio recording page and tap it to stop and tap again to start?
I tried to put the record function in initstate but it didn't work
void initState() {
super.initState();
initRecorder();
record();
}
