containsMatcherType<T extends TextMatcher> method
Whether the iterable contains one or more TextElements
that have type T
as matcherType
.
Pass an index number to the matcherIndex
argument if the source
list contains elements resulting from different matchers of the
same type and therefore specifying only the type is not enough.
Implementation
bool containsMatcherType<T extends TextMatcher>({int? matcherIndex}) {
return matcherIndex == null
? any((e) => e.matcherType == T)
: any((e) => e.matcherType == T && e.matcherIndex == matcherIndex);
}
