Use ; instead of {} for empty constructor bodies.

Details

#

From Effective Dart:

DO use ; instead of {} for empty constructor bodies.

In Dart, a constructor with an empty body can be terminated with just a semicolon. This is required for const constructors. For consistency and brevity, other constructors should also do this.

BAD:

dart
class Point {
  int x, y;
  Point(this.x, this.y) {}
}

GOOD:

dart
class Point {
  int x, y;
  Point(this.x, this.y);
}

Enable

#

To enable the empty_constructor_bodies rule, add empty_constructor_bodies under linter > rules in your analysis_options.yaml file:

analysis_options.yaml
yaml
linter:
  rules:
    - empty_constructor_bodies

If you're instead using the YAML map syntax to configure linter rules, add empty_constructor_bodies: true under linter > rules:

analysis_options.yaml
yaml
linter:
  rules:
    empty_constructor_bodies: true
