Match class
A result from searching within a string.
A Match or an Iterable of Match objects is returned from Pattern matching methods.
The following example finds all matches of a RegExp in a String and iterates through the returned iterable of Match objects.
RegExp exp = new RegExp(r"(\w+)");
String str = "Parse my string";
Iterable<Match> matches = exp.allMatches(str);
for (Match m in matches) {
String match = m.group(0);
print(match);
}
The output of the example is:
Parse
my
string
Some patterns, regular expressions in particular, may record substrings that were part of the matching. These are called groups in the Match object. Some patterns may never have any groups, and their matches always have zero groupCount.
Constructors
- Match()
Properties

read-only
- Returns the index in the string after the last character of the match.
- groupCount → int
read-only
- Returns the number of captured groups in the match. [...]
- input → String
read-only
- The string on which this match was computed.
- pattern → Pattern
read-only
- The pattern used to search in input.
- start → int
read-only
- Returns the index in the string where the match starts.
- hashCode → int
read-only, inherited
- The hash code for this object. [...]
- runtimeType → Type
read-only, inherited
- A representation of the runtime type of the object.
Methods

- Returns the string matched by the given
group
. [...] - groups(List<int> groupIndices) → List<String>
- Returns a list of the groups with the given indices. [...]
