Versions

3.x.x

Starting from the 3.x version, OKToast provides a null-safety version, the specific introduction of null-safety can be viewed in dart or flutter.

The 2.3.2 version is the last version that does not support null-safety.

About version 1.x

if you use OKToast 1.x, Please use the 1.x branch, and read version readme.

Proposed migration to 2.x version. The new version does not require buildContext.

And you can completely customize the style of toast, because now you can use showToastWidget.

Usage

1. Add library to your pubspec.yaml

flutter pub add oktoast

2. Import library in dart file

import 'package:oktoast/oktoast.dart';

3. Wrap your app widget

OKToast(
  /// set toast style, optional
  child:MaterialApp()
);

Tips: If you happened error like: No MediaQuery widget found, you can try to use this code to include OKToast to your App.

MaterialApp(
  builder: (BuildContext context, Widget? widget) {
    return OKToast(child: widget);
  },
);

4. Call method showToast

showToast('content');

// position and second have default value, is optional
showToastWidget(Text('hello oktoast'));

Explain

There are two reasons why you need to wrap MaterialApp

  1. Because this ensures that toast can be displayed in front of all other controls
  2. Context can be cached so that it can be invoked anywhere without passing in context
