require_trailing_commas

Use trailing commas for all parameter lists and argument lists.

此规则自 Dart 2.14 版本起可用。

此规则提供 快速修复 。

DO use trailing commas for all multi-line parameter lists and argument lists. A parameter list or argument list that fits on one line, including the opening parenthesis and closing parenthesis, does not require a trailing comma.

BAD:

void run() {
  method('does not fit on one line',
      'test test test test test test test test test test test');
}

GOOD:

void run() {
  method(
    'does not fit on one line',
    'test test test test test test test test test test test',
  );
}

EXCEPTION: If the final argument in an argument list is positional (vs named) and is either a function literal with curly braces, a map literal, a set literal, or a list literal, then a trailing comma is not required. This exception only applies if the final argument does not fit entirely on one line.

NOTE: This lint rule assumes that code has been formatted with dart format and may produce false positives on unformatted code.

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

linter:
  rules:
    - require_trailing_commas
