async_loader

A flutter plugin for loading content asynchronously.

Example

Usage

To use this plugin, add async_loader as a dependency in your pubspec.yaml file.

Create instance

getMessage() async {
  return new Future.delayed(TIMEOUT, () => 'Welcome to your async screen');
}

...

var _asyncLoader = new AsyncLoader(
    key: _asyncLoaderState,
    initState: () async => await getMessage(),
    renderLoad: () => new CircularProgressIndicator(),
    renderError: ([error]) =>
        new Text('Sorry, there was an error loading your joke'),
    renderSuccess: ({data}) => new Text(data),
);

Trigger reload

class ExampleApp extends StatelessWidget {
  final GlobalKey<AsyncLoaderState> _asyncLoaderState =
      new GlobalKey<AsyncLoaderState>();
  
  reload() {
      _asyncLoaderState.currentState.reloadState()
  }
}

Full Example

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:async_loader/async_loader.dart';

void main() {
  runApp(new ExampleApp());
}

class ExampleApp extends StatelessWidget {
  final GlobalKey<AsyncLoaderState> _asyncLoaderState =
      new GlobalKey<AsyncLoaderState>();

  @override
  Widget build(BuildContext context) {
    var _asyncLoader = new AsyncLoader(
      key: _asyncLoaderState,
      initState: () async => await getMessage(),
      renderLoad: () => new CircularProgressIndicator(),
      renderError: ([error]) =>
          new Text('Sorry, there was an error loading your joke'),
      renderSuccess: ({data}) => new Text(data),
    );

    return new MaterialApp(
        title: 'Async Loader Demo',
        theme: new ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: new Scaffold(
          appBar: new AppBar(title: buildTitle('Async Loader Demo')),
          body: new Center(child: _asyncLoader),
          floatingActionButton: new FloatingActionButton(
            onPressed: () => _asyncLoaderState.currentState.reloadState(),
            tooltip: 'Reload',
            child: new Icon(Icons.refresh),
          ),
        ));
  }
}

const TIMEOUT = const Duration(seconds: 5);

getMessage() async {
  return new Future.delayed(TIMEOUT, () => 'Welcome to your async screen');
}

buildTitle(String title) {
  return new Padding(
    padding: new EdgeInsets.all(10.0),
    child: new Text('Async Loader Demo'),
  );
}

Suggestions

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Fix analysis and formatting issues.

    Analysis or formatting checks reported 1 hint.

    Run flutter format to format lib/async_loader.dart.
