🔗 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: ParsedType.EMAIL, // predefined type can be any of this ParsedTypes
  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
)

You can also set RegexOption for the custom regex pattern like so:

MatchText(
  pattern: r"\B#+([\w]+)\b", // a custom pattern to match
  regexOptions: RegexOptions(
    multiLine : false,
    caseSensitive : false,
    unicode : false,
    dotAll : false
  ),
  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
  },
),
