flatten method

@useResult Parser<String> flatten([ String? message ])

Returns a parser that discards the result of the receiver and answers the sub-string its delegate consumes.

If a message is provided, the flatten parser can switch to a fast mode where error tracking within the receiver is suppressed and in case of a problem message is reported instead.

For example, the parser letter().plus().flatten() returns 'abc' for the input 'abc'. In contrast, the parser letter().plus() would return ['a', 'b', 'c'] for the same input instead.

Implementation

@useResult
Parser<String> flatten([String? message]) => FlattenParser<R>(this, message);
