The Flutter team has a static function on MaterialStateProperty:

static MaterialStateProperty<T> all<T>(T value)

We would like to have a dart fix that will allow us to replace invocations of .all with a call to a constructor for a new class that implements MaterialStateProperty<T>:

const MaterialStatePropertyAll(this.value);

So instead of:

final color = MaterialStateProperty<Color>.all(Colors.blue);

We want:

const color MaterialStatePropertyAll<Color>(Colors.blue);

Looking at the docs for fixes, there doesn't appear to be a way to define this kind of transform. If possible this would be a nice feature for us.
