usage

init (run this before start, so we could check if file with given name already exists)

var recorder = flutteraudiorecorder("filename", audioformat.aac);
await _recorder.initialized;

or

var recorder = flutteraudiorecorder("filename.mp4"); // .wav .aac .m4a
await _recorder.initialized;

start recording

await recorder.start();
var recording = await recorder.current(channel: 0);

get recording details

var current = await recording.current(channel: 0);
// print(current.status);

you could use a timer to access details every 50ms(simply cancel the timer when recording is done)

new timer.periodic(tick, (timer t) async {
        var current = await recording.current(channel: 0);
        // print(current.status);
        setstate(() {
        });
      });
