Always check permission first(it will request permission if permission has not been set to true/false yet, otherwise it will return the result of recording permission)
bool hasPermission = await AnotherAudioRecorder.hasPermissions;

Initialize (run this before start, so we could check if file with given name already exists)
var recorder = AnotherAudioRecorder("file_path.mp4"); // .wav .aac .m4a
await recorder.initialized;

or
var recorder = AnotherAudioRecorder("file_path", audioFormat: AudioFormat.AAC); // or AudioFormat.WAV
await recorder.initialized;

// print(current.status);
setState(() {
