📛 Flutter Mentions

A simple flutter input widget to add @ mentions functionality to your app

Install 📦

To use this package, add flutter_mentions as a dependency in your pubspec.yaml file.

You will need to add flutter_mentions to your pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  flutter_mentions:

Then, run flutter packages get in your terminal.

Usage 💻

To use this package you must first wrap your top most widget with Portal as this package uses flutter_portal to show the suggestions list.

[Portal], is the equivalent of [Overlay].

This widget will need to be inserted above the widget that needs to render under your overlays.

If you want to display your overlays on the top of everything, a good place to insert that [Portal] is above MaterialApp:

Portal(
  child: MaterialApp(
    ...
  )
);

(works for CupertinoApp too)

This way [Portal] will render above everything. But you could place it somewhere else to change the clip behavior.

Frequently asked questions

1. How do I can access to the the editing controller? A. To get the control of TextEditingController just use a Global key more info can be found here #13. This will also allow you to access the text & markupText.
