Lint: use shorter name for local variable

[danylo-safonov-solid]

If variable is used within x lines (e.g. make it 10, or make it configurable) prefer a shorter name, because it can probably deduced from context

final selectedNames = users.map((u) => u.name).where((n) => n.isSelected).toList();

final selectedNames = users.map((user) => user.name).where((name) => name.isSelected).toList();

first example is easier to read
