m method

Map m(
  1. String key, {
  2. Map defaultValue = const {},
  3. bool showLog = true,
})

获取 value 转 bool

Implementation

Map m(String key, {Map defaultValue = const {}, bool showLog = true}) {
  if (!containsKey(key)) {
    _log('当前map不存在 key:[$key]', showLog);
    return defaultValue;
  }
  final value = this[key];
  if (value is Map) return value;
  _log('${value.runtimeType} [$key]=$value => map:$defaultValue', showLog);
  return defaultValue;
}
