seq method

@useResult Parser<List> seq(Parser other)

Returns a parser that accepts the receiver followed by other. The resulting parser returns a list of the parse result of the receiver followed by the parse result of other. Calling this method on an existing sequence code does not nest this sequence into a new one, but instead augments the existing sequence with other.

For example, the parser letter().seq(digit()).seq(letter()) accepts a letter followed by a digit and another letter. The parse result of the input string 'a1b' is the list <dynamic>['a', '1', 'b'].

Implementation

@useResult
Parser<List<dynamic>> seq(Parser other) => switch (this) {
      SequenceParser(children: final children) =>
        [...children, other].toSequenceParser(),
      _ => [this, other].toSequenceParser()
    };
