toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() =>
    'LogFilter('
    '${[
      if (after != null) 'after: $after',
      if (before != null) 'before: $before',
      if (levels.isNotEmpty) 'levels: ${levels.map((level) => level.name).join(',')}',
      if (tags.isNotEmpty) 'tags: $tags',
      if (attributes.isNotEmpty) 'attributes: $attributes',
      if (text.isNotEmpty) 'text: "$text"',
    ].join(', ')}'
    ')';
