How to convert Visual Studio Code snippets for use in Android Studio

Create a Dart scratch file (Cmd+Shift+N)
Paste in the body of any snippet into the scratch file
Remove the double quotes and extra commas (Cmd+R is the replace command)
Replace the token placeholders with variable names (${1} => $placeholderName$)
Highlight the transformed code, and go to Tools > Save as Live Template
Add the abbreviation and description as seen in the dialog box below
Make sure to add a default value to each variable used (see the edit variables button on live template dialog below)
Once saved you can use the stkv template anywhere in the Flutter/Dart scope

Requires just terminal, nano, vi and sudo rights

Works on MacOS Monterrey+

Tips

Everything needs to be run in Terminal
Check your man search path using manpath
Type manpath to see available locations
Use share for pages accessible to all users
Some versions of man epect to see gzipped files
Check the folders of existing man pages to view file formats expected

How to pass arguments to a widget using a variable:

	Super Constructor in Dart
	In dart, the subclass can inherit all the variables and methods of the parent class, with the use of extends keyword but it can’t inherit constructor of the parent class. To do so we make use of super constructor in the dart. There are two ways to call super constructor:

	Implicitly
	Explicitly
	When calling explicitly we make use of super constructor as:
