unreachable_from_main

Unreachable top-level members in executable libraries.

此规则自 Dart 2.19 版本起可用。

此规则提供 快速修复 。

Any member declared in an executable library should be used directly inside that library. An executable library is a library that contains a main top-level function or that contains a top-level function annotated with @pragma('vm:entry-point')). Executable libraries are not usually imported and it's better to avoid defining unused members.

This rule assumes that an executable library isn't imported by other libraries except to execute its main function.

BAD:

main() {}
void f() {}

GOOD:

main() {
  f();
}
void f() {}

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

linter:
  rules:
    - unreachable_from_main
