A Flutter package to parse text and make them into linkified text widget
Flutter Parsed text
A Flutter package to parse text and extract parts using predefined types like url, phone and email and also supports Regex.
Usage ?
To use this package, add flutter_parsed_text as a dependency in your pubspec.yaml file.
import 'package:flutter_parsed_text/flutter_parsed_text.dart';
Working ⚙️
ParsedText can receive this paramters & all the RichText parameters:
text: Text that will be parsed and rendered.
style: It takes a TextStyle object as it's property to style all the non links text objects.
parse: Array of MatchText object - used for defining structure for pattern matching .
MatchText(
type: "email", // predefined type can be any of this email, phone, url or custom
style: TextStyle(
color: Colors.red,
fontSize: 24,
), // custom style to be applied to this matched text
onTap: (url) {
// do something here with passed url
}, // callback funtion when the text is tapped on
),
You can also define a custom pattern like this:
MatchText(
pattern: r"\B#+([\w]+)\b", // a custom pattern to match
style: TextStyle(
color: Colors.pink,
fontSize: 24,
), // custom style to be applied to this matched text
onTap: (url) async {
// do something here with passed url
}, // callback funtion when the text is tapped on
)
A boolean that show a diffrent text and passes a diffrent text to the callback
eg: Your str is "Mention [@michel:5455345]" where 5455345 is ID of this user which will be passed as parameter to the callback funtion and @michel the value to display on interface. Your pattern for ID & username extraction : /\[(@[^:]+):([^\]]+)\]/i
Displayed text will be :
Mention ^^@michel^^
MatchText(
pattern: r"\[(@[^:]+):([^\]]+)\]",
style: TextStyle(
color: Colors.green,
fontSize: 24,
),
// you must return a map with two keys
// [display] - the text you want to show to the user
// [value] - the value underneath it
renderText: ({String str, String pattern}) {
Map<String, String> map = Map<String, String>();
RegExp customRegExp = RegExp(pattern);
Match match = customRegExp.firstMatch(str);
map['display'] = match.group(1);
map['value'] = match.group(2);
return map;
},
onTap: (url) {
// do something here with passed url
},
),
