Flutter add a Panic button for Deleting App for himself, as Cleaning all Datas and

Question

I want to add a Panic button in my Flutter App, if i hold 3 Seconds (on Volume Down button or Up - Power it doesnt matter), the app will be completely uninstalled. I tried this with Automate App but its not supporting to the Uninstall method. I can use the Hardware buttons , but how i can use the Uninstalling Command in Flutter without Root ? Thanks for all Respons,

here some Links which i test but doesnt work.
