matches method
override
Does the matching of the actual vs expected values.
item
is the actual value. matchState
can be supplied
and may be used to add details about the mismatch that are too
costly to determine in describeMismatch.
Implementation
@override
bool matches(Object? item, Map matchState) {
try {
var f = featureValueOf(item);
if (_matcher.matches(f, matchState)) return true;
addStateInfo(matchState, {'custom.feature': f});
} catch (exception, stack) {
addStateInfo(matchState, {
'custom.exception': exception.toString(),
'custom.stack': Chain.forTrace(stack)
.foldFrames(
(frame) =>
frame.package == 'test' ||
frame.package == 'stream_channel' ||
frame.package == 'matcher',
terse: true)
.toString()
});
}
return false;
