本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Verify how missing mandatory options behave differently depending on whether they have a registered callback.
- 符号
-
- ArgParser.parse
- ArgResults.[]
- ArgResults.option
- 环境
- dart

契约
- ArgParser.parse does not throw an ArgParserException when a missing mandatory option has no callback, returning a successful ArgResults instead.
- Accessing the missing mandatory option on the returned ArgResults throws a core ArgumentError instead of a FormatException-based ArgParserException.
- ArgParser.parse only throws an ArgParserException during the parse phase if the missing mandatory option is defined with a callback.
- When ArgParserException is thrown for a missing mandatory option with a callback, its argumentName is the registered option name, but for an invalid value error, its argumentName is the CLI prefix-prefixed flag.
