unnecessary_ late
Learn about the unnecessary_late linter rule.
Don't specify the late modifier when it is not
needed.
Details
#
DO not specify the late modifier
for top-level and static variables when the declaration
contains an initializer.
Top-level and static variables with initializers are already
evaluated lazily as if they are marked late.
BAD:
late String badTopLevel = '';
GOOD:

BAD:

static late String badStatic = '';
}
GOOD:
class GoodExample {
late String goodStatic;
}
