Tutorial Membuat Aplikasi Blog Flutter Backend WordPress API

by with No Comment APIFlutterTeknologiTutorialWordpress

Artikel ini akan membahas tutorial bagaimana membuat aplikasi blog sederhana menggunakan flutter dengan menggunakan wordpress sebagai API-nya, studi kasus kali ini menggunakan backend.

Langkah pertamanya adalah membuat project di flutter

flutter create blogwp

create flutter project

main.dart

Ubah bagian main.dart pada folder lib

import 'package:flutter/material.dart';
void main() {
  runApp(const MyApp());
}
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}
class MyHomePage extends StatefulWidget {
  const MyHomePage({ Key? key,  }) : super(key: key);
  @override
  _MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('belajarflutterapp'),
      ),
    );
  }
}

Add Dependency

lalu kita siapkan package yang dibutuhkan dengan menggunakan shortcut ctrl + shift + P, tampilannya akan seperti di bawah ini :

Dart :add dependency

Function Get

 

Selanjutnya kita akan membuat function / fungsi yang berfungsi untuk mengirimkan permintaan ke aplikasi mobile yang ingin kita buat.

Future<List> getPosts() async {
var response = await http.get(
Uri.parse("https://belajarflutter.com/wp-json/wp/v2/posts?_embed"),
headers: {
"Accept": "application/json",
},
);
return jsonDecode(response.body);
}

initstate

lalu tambahkan function getPosts ke dalam void initstate

 

void initState() {
getPosts();
super.initState();
}

Untuk full code nya di atas ada di bawah ini :

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
Future<List> getPosts() async {
var response = await http.get(
Uri.parse("https://belajarflutter.com/wp-json/wp/v2/posts?_embed"),
headers: {
"Accept": "application/json",
},
);
return jsonDecode(response.body);
}
@override
void initState() {
getPosts();
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(
'BelajarFlutterApps',
),
),
body: FutureBuilder(
future: getPosts(),
builder: (BuildContext context, AsyncSnapshot<dynamic> snapshot) {
if (snapshot.hasData) {
return ListView.builder(
itemCount: snapshot.data.length,
itemBuilder: (context, index) {
Map posts = snapshot.data[index];
return Text(posts['title']['rendered']);
});
}
return CircularProgressIndicator();
},
),
);
}
}

Output Sementara

Next Step

langkah selanjutnya kita akan tampung datanya di dalam column dan sedikit merapikan user interfacenya

Column

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
Future<List> getPosts() async {
var response = await http.get(
Uri.parse("https://belajarflutter.com/wp-json/wp/v2/posts?_embed"),
headers: {
"Accept": "application/json",
},
);
return jsonDecode(response.body);
}
@override
void initState() {
getPosts();
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(
'BelajarFlutterApps',
),
),
body: FutureBuilder(
future: getPosts(),
builder: (BuildContext context, AsyncSnapshot<dynamic> snapshot) {
if (snapshot.hasData) {
return ListView.builder(
itemCount: snapshot.data.length,
itemBuilder: (context, index) {
Map posts = snapshot.data[index];
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
posts['title']['rendered'],
style: TextStyle(
fontSize: 20.0,
color: Colors.blueAccent,
fontWeight: FontWeight.bold,
),
),
],
);
});
}
return CircularProgressIndicator();
},
),
);
}
}

Card dan Padding

tambahkan card dan padding pada desain yang kita buat

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
Future<List> getPosts() async {
var response = await http.get(
Uri.parse("https://belajarflutter.com/wp-json/wp/v2/posts?_embed"),
headers: {
"Accept": "application/json",
},
);
return jsonDecode(response.body);
}
@override
void initState() {
getPosts();
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(
'BelajarFlutterApps',
),
),
body: FutureBuilder(
future: getPosts(),
builder: (BuildContext context, AsyncSnapshot<dynamic> snapshot) {
if (snapshot.hasData) {
return ListView.builder(
itemCount: snapshot.data.length,
itemBuilder: (context, index) {
Map posts = snapshot.data[index];
return Card(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
posts['title']['rendered'],
style: TextStyle(
fontSize: 20.0,
color: Colors.blueAccent,
fontWeight: FontWeight.bold,
),
),
],
),
),
);
});
}
return CircularProgressIndicator();
},
),
);
}
}

Tampilkan Gambar

return ListView.builder(
itemCount: snapshot.data.length,
itemBuilder: (context, index) {
Map posts = snapshot.data[index];
return Card(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Image.network(
posts['_embedded']['wp:featuredmedia'][0]['source_url'],
),
Text(
posts['title']['rendered'],
style: TextStyle(
fontSize: 20.0,
color: Colors.blueAccent,
fontWeight: FontWeight.bold,
),
),
],
),
),
);
});
Output finalnya adalah seperti di bawah ini :

Full Code nya : 

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
Future<List> getPosts() async {
var response = await http.get(
Uri.parse("https://belajarflutter.com/wp-json/wp/v2/posts?_embed"),
