I'm trying to create a Flutter note-taking app for myself which will enable me to record and organise my voice notes.
I want the functionality to be such:
- Screen is Off; When I long press the volume down button (or another hardware button) >> App launches and audio recording starts;
- When I release the button, Audio recording stops and audio is saved; then I am presented with a screen to select tags regarding the previous recording.
I have researched various packages and implementations (such as the HardwareKeyboard class) that can be used but I am unable to find clarity with regards to how this specific functionality can be achieved.
I don't need a very detailed response, but I'd love it if someone could point me in the right direction/resources with regards to the following queries specifically:
- How to launch app and startFunction( ) when volume down is long pressed
- How to detect when the button is released and stopFunction( ).then(nextFunction( ))
