Hello Koders,
am building an app that have floating action btn inside , so i wanted to disable the native back btn on the phone or tablet how can i disable it please , i was searching the community i didn’t found my answer any help please ?

Just put this block in your screen and leave it empty…



Tried it , but not working , am using 1 screen , but many invisible vertical scroll arrangement so on pressing on back btn its take me to screen1 the splash screen and keep loading

If it’s empty, it shouldn’t do anything


It works like this <

You can try something like :

While Back Click counter = 1, //your code.
Else, leave blank.
