Pattern: Unnecessary getter
Issue: -
PREFER using a public final field instead of a private field with a public getter.
If you have a field that outside code should be able to see but not assign to
(and you don't need to set it outside of the constructor), a simple solution
that works in many cases is to just mark it final.
Example of correct code:
class Box {
final contents = [];
}Example of incorrect code:
class Box {
var _contents;
get contents => _contents;
}
