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() =>
    'GroupSubscriptionLimitException: Adding "$attemptedGroupId" would '
    'produce an endpoint name of $currentLength bytes, exceeding the '
    '$maxLength-byte limit. Currently subscribed to: '
    '${currentGroupIds.join(", ")}. '
    'Unsubscribe from a group or use shorter group names.';
