Please help I don't know what I'm doing wrong. When I add in this custom action then try to save it , Flutterflow will say Noisemeter action declaration not found which then leads to the custom action not being saved. Here is my custom action code :
import 'dart:async';
import 'package:noise_meter/noise_meter.dart';
import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';
void main() => runApp(NoiseMeterApp());
class NoiseMeterApp extends StatefulWidget {
@override
NoiseMeterAppState createState() => NoiseMeterAppState();
}
class _NoiseMeterAppState extends State<NoiseMeterApp> {
bool _isRecording = false;
NoiseReading? _latestReading;
StreamSubscription<NoiseReading>? _noiseSubscription;
NoiseMeter? noiseMeter;
@override
void dispose() {
_noiseSubscription?.cancel();
super.dispose();
}
void onData(NoiseReading noiseReading) =>
setState(() => _latestReading = noiseReading);
void onError(Object error) {
print(error);
stop();
}
/// Check if microphone permission is granted.
Future<bool> checkPermission() async => await Permission.microphone.isGranted;
/// Request the microphone permission.
Future<void> requestPermission() async =>
await Permission.microphone.request();
/// Start noise sampling.
Future<void> start() async {
// Create a noise meter, if not already done.
noiseMeter ??= NoiseMeter();
// Check permission to use the microphone.
//
// Remember to update the AndroidManifest file (Android) and the
// Info.plist and pod files (iOS).
if (!(await checkPermission())) await requestPermission();
// Listen to the noise stream.
_noiseSubscription = noiseMeter?.noise.listen(onData, onError: onError);
setState(() => _isRecording = true);
}
/// Stop sampling.
void stop() {
_noiseSubscription?.cancel();
setState(() => _isRecording = false);
}
@override
Widget build(BuildContext context) => MaterialApp(
home: Scaffold(
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(

margin: EdgeInsets.only(top: 20),

Container(
child: Text(

])),
])),
floatingActionButton: FloatingActionButton(
backgroundColor: _isRecording ? Colors.red : Colors.green,
child: _isRecording ? Icon(Icons.stop) : Icon(Icons.mic),
onPressed: _isRecording ? stop : start,
