sized_box_shrink_expand

Use SizedBox shrink and expand named constructors.

此规则自 Dart 2.16 版本起可用。

Use SizedBox.shrink(...) and SizedBox.expand(...) constructors appropriately.

Either the SizedBox.shrink(...) or SizedBox.expand(...) constructor should be used instead of the more general SizedBox(...) constructor when one of the named constructors capture the intent of the code more succinctly.

Examples

BAD:

Widget buildLogo() {
  return SizedBox(
    height: 0,
    width: 0,
    child: const MyLogo(),
  );
}

Widget buildLogo() {
  return SizedBox(
    height: double.infinity,
    width: double.infinity,
    child: const MyLogo(),
  );
}

GOOD:

Widget buildLogo() {
  return SizedBox.shrink(
    child: const MyLogo(),
  );
}

Widget buildLogo() {
  return SizedBox.expand(
    child: const MyLogo(),
  );
}

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

linter:
  rules:
    - sized_box_shrink_expand
