toString method
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() => 'SystemMessage {'
'Operator Location Type: $operatorLocationType, '
'Operator Location: $operatorLocation, '
'Operator Altitude: $operatorAltitude m, '
'Area Count: $areaCount, '
'Area Radius: $areaRadius m, '
'Area Ceiling: $areaCeiling m, '
'Area Floor: $areaFloor m, '
'UA Classification: $uaClassification, '
'Timestamp: $timestamp'
'}';
