Not working when i use @jhon.234 (dot)

Please make it possible to use dots, underscores in usernames.

@moinkhan780 you should be able to do this. There’s a property of the FlutterTagger constructor called searchRegex that you can specify to allow all kinds of characters. By default the regex is ^[a-zA-Z-]*$ which only matches letters of the English alphabet.

I tried adding regex for space but it does not seem to have color highlight on tags with space. The tags work, its just the color highlights on tags with space fails.

@ganadevprajapathy apart from the search regex, there's another regex used to match and format tags

fluttertagger/lib/src/tagger.dart

Line 955 in 2786c9d

pattern ??= RegExp(r'([@#]\w+\#.+?\#)');

You also need to look at the tagTextFormatter.
If you've not provided your own formatting rules via tagTextFormatter and an accompanying regex via FlutterTaggerController.formatTags(), then defaults are used which do not allow spacing in tags.

What to do:

After adding a tag using the controller, call formatTags on the controller, pass it your regex which extracts tag name and ID with space allowed. You may also need to pass it a parser. You can see how that is implemented below for the default format:

fluttertagger/lib/src/tagger.dart

Lines 947 to 1010 in 2786c9d

	void _formatTags([
	RegExp? pattern,
	List<String> Function(String)? parser,
	]) {
	_clearCallback?.call();
	_text = text;
	String newText = text;
	pattern ??= RegExp(r'([@#]\w+\#.+?\#)');
	parser ??= (value) {
	final split = value.split("#");
	if (split.length == 4) {
	// default hashtag group match (tag and id)
	return [split[1].trim(), split[2].trim()];
	}
	// default user mention group match (name and id)
	final id = split.first.trim().replaceFirst("@", "");
	return [id, split[split.length - 2].trim()];
	};
	final matches = pattern.allMatches(text);
	int diff = 0;
	for (var match in matches) {
	try {
	final matchValue = match.group(1)!;
	final idAndTag = parser(matchValue);
	final triggerChar = text.substring(match.start, match.start + 1);
	final tag = "$triggerChar${idAndTag.last.trim()}";
	final startIndex = match.start;
	final endIndex = startIndex + tag.length;
	newText = newText.replaceRange(
	startIndex - diff,
	startIndex + matchValue.length - diff,
	tag,
	);
	final taggedText = TaggedText(
	startIndex: startIndex - diff,
	endIndex: endIndex - diff,
	text: tag,
	);
	_tags[taggedText] = idAndTag.first;
	_trie.insert(taggedText);
	diff += matchValue.length - tag.length;
	} catch (e) {
	debugPrint(e.toString());
	}
	}
	if (newText.isNotEmpty) {
	_runDeferedAction(() => text = newText);
	_runDeferedAction(
	() => selection = TextSelection.fromPosition(
	TextPosition(offset: newText.length),
	),
	);
	}
	}

I am trying very hard to getting this to work but I can't figure it out. I can't use whitespace in the "name" property of a tag. Is it possible for you to provide a working example?
