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() => [
'CollectionConfiguration(',
[
if (channels != null) 'channels: $channels',
if (documentIds != null) 'documentIds: $documentIds',
if (pushFilter != null) 'PUSH-FILTER',
if (pullFilter != null) 'PULL-FILTER',
if (conflictResolver != null) 'CUSTOM-CONFLICT-RESOLVER',
].join(', '),
')'
].join();
