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() {
  return '''
        Exception: Metadata not found for block: $blockNumber.'

        Try adding the SpecVersion for blockNumber: $blockNumber.
        ```
          chainObject.initSpecVersionFromFile('../../versions.json');

          or

          final specVersion = SpecVersion.fromJson( { specJson } );

          chainObject.addSpecVersion(specVersion);
        ```
        ''';
}
