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() {
final content = [
if (isLoading && this is! AsyncLoading) 'isLoading: $isLoading',
if (progress case final progress?) 'progress: $progress',
if (hasValue) 'value: $value',
if (_error != null) ...[
'error: $error',
'stackTrace: $stackTrace',
if (_errorFilled!.retrying) 'retrying',
],
if (_value?.kind case final valueSource?)
'valueSource: ${valueSource.name}',
].join(', ');
return '$_displayString<$ValueT>($content)';
}
