Flutter pure toast library

pure flutter toast library

A pure dart toast Library.

You can completely customize the style of toast.

Usage

1. Add library to your pubspec.yaml

latest version: 

dependencies:
  oktoast: ^3.0.0 # such as version, you need use the latest version of pub.

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 next code to include oktoast to your App.

MaterialApp(builder: (context, 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
