Use ; instead of {} for empty constructor bodies.

此规则自 Dart 2.0 版本起可用。

此规则提供 快速修复 。

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:

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

GOOD:

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

要启用 empty_constructor_bodies 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 empty_constructor_bodies ：

linter:
  rules:
    - empty_constructor_bodies
