I'm working with Flutter and Android Studio. I am trying to block *ahem* Group some line of codes so that I can just hide it by clicking the plus icon on the left hand side.
How to group a line of codes as a single block in Android Studio and/or Flutter?
If I am not getting you wrong , you are talking about The Code Folding shortcuts in Android Studio. They allow us to fold Code Blocks & Region Blocks so we can have more fine grained control over what code we are looking at in any given moment. Have you checked these from official page:
Collapse/expand current code block Control+minus or Control+plus Command+minus or Command+plus
Collapse/expand all code blocks Control+Shift+minus or Control+Shift+plus Command+Shift+minus or Command+Shift+plus
For creating a region you can do this simply :
//start region method
//your work here
//endregion
to open this
control+shift+ (plus +)
to close the region:
control+shift+ (minus -)
