provide_deprecation_message

Provide a deprecation message, via @Deprecated("message").

此规则自 Dart 2.2 版本起可用。

_规则集：core , recommended , flutter _

DO specify a deprecation message (with migration instructions and/or a removal schedule) in the Deprecated constructor.

BAD:

@deprecated
void oldFunction(arg1, arg2) {}

GOOD:

@Deprecated("""
[oldFunction] is being deprecated in favor of [newFunction] (with slightly
different parameters; see [newFunction] for more information). [oldFunction]
will be removed on or after the 4.0.0 release.
""")
void oldFunction(arg1, arg2) {}

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

linter:
  rules:
    - provide_deprecation_message
