use_string_buffers

Use string buffers to compose strings.

此规则自 Dart 2.0 版本起可用。

DO use string buffers to compose strings.

In most cases, using a string buffer is preferred for composing strings due to its improved performance.

BAD:

dartString foo() {
  final buffer = '';
  for (int i = 0; i < 10; i++) {
    buffer += 'a'; // LINT
  }
  return buffer;
}

GOOD:

dartString foo() {
  final buffer = StringBuffer();
  for (int i = 0; i < 10; i++) {
    buffer.write('a');
  }
  return buffer.toString();
}

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

analysis_options.yaml
yamllinter:
  rules:
    - use_string_buffers

除非另有说明，否则本网站上的文档反映的是 Dart 3.6.0。页面最后更新于 2025-02-05。查看源代码或报告问题.
