Install

Install by adding this package to your pubspec.yaml:

dependencies:
  linkify: ^5.0.0

Usage

import 'package:linkify/linkify.dart';

linkify("Made by https://cretezy.com person@example.com");
// Output: [TextElement: 'Made by ', UrlElement: 'https://cretezy.com' (cretezy.com), TextElement: ' ', EmailElement: 'person@example.com' (person@example.com)]

Options

You can pass LinkifyOptions to the linkify method to change the humanization of URLs (turning https://example.com to example.com):

linkify("https://cretezy.com");
// [UrlElement: 'https://cretezy.com' (cretezy.com)]

linkify("https://cretezy.com", options: LinkifyOptions(humanize: false));
// [UrlElement: 'https://cretezy.com' (https://cretezy.com)]

• humanize: Removes http/https from shown URLs
• removeWww: Removes www. from shown URLs
• looseUrl: Enables loose URL parsing (should parse most URLs such as abc.com/xyz)
  • defaultToHttps: When used with [looseUrl], default to https instead of http
• excludeLastPeriod: Excludes . at end of URLs

Linkifiers

You can pass linkifiers to linkify as such:

linkify("@cretezy", linkifiers: [UserTagLinkifier()]);

Available linkifiers:

• EmailLinkifier
• UrlLinkifier
• PhoneNumberLinkifier
• UserTagLinkifier

Custom Linkifier

You can write custom linkifiers for phone numbers or other types of links. Look at the URL linkifier for an example.

This is the flow:

• Calls parse in the linkifier with a list of LinkifyElement. This starts as [TextElement(text)]
• Your parsers then splits each element into it's parts. For example, [TextElement("Hello https://example.com")] would become [TextElement("Hello "), UrlElement("https://example.com")]
• Each parsers is ran in order of how they are passed to the main linkify function. By default, this is URL and email linkifiers
