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() => '$runtimeType('
'"$url",'
'scale: $scale,'
'header: $header,'
'useDiskCache: $useDiskCache,'
'retryLimit: $retryLimit,'
'retryDuration: $retryDuration,'
'retryDurationFactor: $retryDurationFactor,'
'timeoutDuration: $timeoutDuration'
')';
