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() {
  final tagInfo = tag != null ? ' with tag "$tag"' : '';
  return 'DependencyNotFoundException: Dependency of type $type$tagInfo is not registered.\n'
      'Please use Dependency.put<$type>($type()) before using Dependency.find<$type>()';
}
