Make simple http requests with a Flutter widget.


  • Uses package http for requests
  • Allows to transform response to a data model
  • supports GET/POST methods

Getting started

Here is a quick look at using the fetch widget:

// import 'dart:convert' as convert;
// import 'package:http/http.dart' as http;

  url: "https://jsonplaceholder.typicode.com/posts/1",
  transform: _toPost,
  builder: (model) {
    if (model.isWaiting) {
      return Text('Loading...');

    if (model.isDone && model.statusCode != 200) {
      return Text(
        'Could not connect to API service. `${model.response.body}`');

    return Column(
      children: <Widget>[
Post _toPost(http.Response response) {
  final json = convert.json.decode(response.body);
  return Post(json['id'], json['title']);

import 'dart:convert' as convert;

import 'package:flutter/material.dart';
import 'package:flutter_fetch_widget/flutter_fetch_widget.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      home: new MyHomePage(title: 'Flutter Demo Home Page'),

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  _MyHomePageState createState() => new _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {

  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text(widget.title),
      body: new Center(
        child: new FetchWidget<Post>(
          url: 'https://jsonplaceholder.typicode.com/posts/1',
          transform: _toPost,
          builder: (fetchPost) {
            if (fetchPost.isWaiting) {
              return new Text('Loading...');

            if (fetchPost.isDone && fetchPost.statusCode != 200) {
              return new Text(
                  'Could not connect to API service. `${fetchPost.response.body}`');

            return new Column(
              children: <Widget>[
                new Text('Id: ${fetchPost.data.id}'),
                new Text('Title: ${fetchPost.data.title}'),
                new RaisedButton(
                    color: Colors.green,
                    textColor: Colors.white,
                    onPressed: () => fetchPost.doFetch(),
                    child: new Text('Refresh')),

Post _toPost(response) {
  final Map<String, dynamic> json = convert.json.decode(response.body);

Maintenance suggestions

The description is too short. (-20 points)

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-v0.1 release. (-10 points)

While there is nothing inherently wrong with versions of 0.0.*, it usually means that the author is still experimenting with the general direction of the API.
