tighten_type_of_initializing_formals
Tighten type of initializing formal.
This rule is available as of Dart 2.12.
Details
#Tighten the type of an initializing formal if a non-null assert exists. This allows the type system to catch problems rather than have them only be caught at run-time.
BAD:
dart
class A {
A.c1(this.p) : assert(p != null);
A.c2(this.p);
final String? p;
}
GOOD:
dart
class A {
A.c1(String this.p);
A.c2(this.p);
final String? p;
}
class B {
String? b;
B(this.b);
}
class C extends B {
B(String super.b);
}
