close_sinks

Close instances of dart:core Sink.

此规则自 Dart 2.0 版本起可用。

DO invoke close on instances of dart:core Sink.

Closing instances of Sink prevents memory leaks and unexpected behavior.

BAD:

class A {
  IOSink _sinkA;
  void init(filename) {
    _sinkA = File(filename).openWrite(); // LINT
  }
}

BAD:

void someFunction() {
  IOSink _sinkF; // LINT
}

GOOD:

class B {
  IOSink _sinkB;
  void init(filename) {
    _sinkB = File(filename).openWrite(); // OK
  }

  void dispose(filename) {
    _sinkB.close();
  }
}

GOOD:

void someFunctionOK() {
  IOSink _sinkFOK; // OK
  _sinkFOK.close();
}

Known limitations

This rule does not track all patterns of Sink instantiations and closures. See linter#1381 for more information.

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

linter:
  rules:
    - close_sinks
