Conditions #

onSuccess = if snapshot.hasData is true
onError = if snapshot.hasError is true
onWaiting = if snapshot.hasData is false

If you want to indicate the data type when it is a success or an error, you need to add the data types as generics Wrx<S, E>

S (Data type when success)
E (Data type when is error)

The package has a class for the error type (StreamException), which receives a generic to indicate the type of error data that you want to use (See example)
Example #
import 'dart:async';

import 'package:flutter/material.dart';
import 'package:widget_rx/widget_rx.dart';
import 'package:widget_rx/exception/stream_exception.dart';

void main() => runApp(
const Init(),
);

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

@override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Widget Reactive',
home: Home(),
);
}
}

class Home extends StatelessWidget {
const Home({super.key});

@override
Widget build(BuildContext context) {
final StreamController<String> streamController =
StreamController<String>();

return Scaffold(
appBar: AppBar(
title: const Text('Example Wrx'),
),
body: Center(
child: Wrx<String, StreamException<String>>(
stream: streamController.stream,
onSuccess: (value) {
return Text(value);
},
onError: (error) {
return Text(error.data);
},
onWaiting: () {
return const CircularProgressIndicator();
},
),
),
);
}
}
