Move voice recording implementation to another widget

[mrahimygk]

We need it to be reusable in main_page and add_note_page

Hii @mrahimygk, Can I work on this issue?

Hey @mrahimygk, Can you help me to locate the voice recording implementation and clarify on the issue?

@kamal-kaur04 We need to record voice in two pages: main_page.dart and add_note_page. The logic is inside main page for now, which prevents us to use that in another pages (look for bool isRecording = false; and FlutterAudioRecorder recorder in main_page.dart). I need a good solution that builds an api to record and show the visualizations dialog.
