Request Easy Loading

The request_easy_loading package helps you to show loading or progress dialog while sending request to server and it doesn't need context for doing that

Getting Started

The request_easy_loading contains the minimal implementation required to create navigator key and pass it to the library

How to Use

Step 1:

Download or clone this repo by using the link below:

https://github.com/sepehr13494/request_easy_loading

Step 2:

Go to project root and execute the following command in console to get the required dependencies:

flutter pub get 

Request Easy Loading Features:

• showLoading
• showProgressDialog

Now, lets dive into the lib folder which has the main code for the application.

Main

Create a navigator key and pass it to the setNavigator method in the request_easy_loading this will manage all the contexts. Also pass the navigator key to your MaterialApp widget.

This helps you to access current context wherever in the app through:

BuildContext currentContext = navigatorKey.currentState!.context;

and let's get back to our project

final navigatorKey = GlobalKey<NavigatorState>();  // add this line

void main() {
  WidgetsFlutterBinding.ensureInitialized();   // add this line
  RequestEasyLoading().setNavigatorKey(navigatorKey);   // add this line
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: navigatorKey, // add this line
      home: HomePage(),
    );
  }
}

And now you can easily use this line to show loading dialog anywhere in your app.

showLoading(){
  RequestEasyLoading().showEasyLoading();
}

or cancel loading with

cancelLoading(){
  RequestEasyLoading().cancelEasyLoading();
}

And for the requests that you need to upload a file and you need to show progress dialog simply use:

showProgressDialog(){
  RequestEasyLoading().showProgressDialog(sent, total);
}

For #dio you can use it like this:

sendFileRequest(){
  dio.post(
      baseUrl,
      data: body,
      onSendProgress:(int sent,int total){
        print("$sent , $total");
        RequestEasyLoading().showProgressDialog(sent,total);
      }
  );
}
