prefer_const_declarations
Prefer const
over final
for declarations.
This rule is available as of Dart 2.0.
This rule has a quick fix available.
Details
#PREFER using const
for constant-valued declarations.
Constant declarations are more hot-reload friendly and allow values to be used in other constant expressions.
BAD:
dart
final o = const <int>[];
class A {
static final o = const <int>[];
}
GOOD:
dart
const o = <int>[];
class A {
static const o = <int>[];
}
