Flutter pasang dalam PC untuk pembangunan mobile apps multi-platform

Build for ios and android with Flutter

Sempena 10 tahun dah terjebak dalam pembangunan apps Android, makanya kita upgrade kepada evolusi Android terkini . Google Flutter menyediakan pembangunan apps mobile multiplatform.

Muatturun dari Flutter.io

Flutter boleh download dari flutter.io, selepas download flutter SDK extract dalam root atau C:

Download flutter SDK and extract in root or C

Seterusnya set path ke flutter/bin dalam environment variable.

System properties – environment variables – path

System properties – environment variables – path – add new path – flutter-bin

Pasang Android Studio + Android SDK

Muatturun installer dari developer.android.com

Download Android Studio from developer.android

Selepas berjaya muat turun (700++MB) teruskan install. Installer tadi cuma mengandungi IDE iaitu IntelliJ. Selepas install selesai anda akan diminta download AndroidSDK dan emulator.

SDK Manager

Android Studio SDK manager to download Android platforms

AVD Manager

Flutter Doctor

Flutter doctor all OK

Tool periksa kesediaan Flutter

Bila dah selesai install flutter dan AndroidSDK – run Flutter Doctor

Jika ada masalah dengan license, run dalam cmd

flutter doctor --android-licenses

 

Dart

Programming language similar to C.

DartLang.org

 

Visual Studio Code

Kod laju tanpa Android Studio. Install the Flutter plugin in VSCode.

Projek baru Flutter dalam VSCode

VSCode View – Command Palette – Flutter-NewProject

Cuba kod ini dalam  main.dart

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget{
  @override
  Widget build (BuildContext context){
    return MaterialApp(
      title: 'Hello Word Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Welcome to Flutter'),
        ),
        body: Center(
          child: Text('Hello World, Flutter'),
        ),
      ),
    );
  }//end Widget
}//end class

Output

Hellowold flutter demo apps

 

Tambah Container baru dalam main.dart

Output

Tambahan fail class baharu, contoh mersing.dart

 

import 'package:flutter/material.dart';

class Mersing extends StatelessWidget{
  @override
  Widget build(BuildContext context){
    return new Container(
      margin: const EdgeInsets.all(10.0),
      padding: EdgeInsets.all(10.0),
      decoration: new BoxDecoration(border: new Border.all(color: Colors.redAccent)),
      child: new Column(
        children: <Widget>[
          //new FlutterLogo(size: 300.0),
          new Text('Flutter @PoliMersing'),
          new Text('http://www.pmj.edu.my/'),
        ]
      ),
    );
  }
}

Sekiranya perlu buat panggilan kepada class Mersing, include di atas dan panggil method Mersing(). Caranya seperti imej di bawah

VSCode call Flutter method from class inclusion

 

Kod penuh main.dart

import 'package:flutter/material.dart';
import 'mersing.dart';//include dart file

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

class MyApp extends StatelessWidget{
  @override
  Widget build (BuildContext context){
    return MaterialApp(
      title: 'Hello Word Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Welcome to Flutter'),
        ),
        body: new Container(
          margin: const EdgeInsets.all(15.0),
          padding: EdgeInsets.all(32.0),
          decoration: new BoxDecoration(border: new Border.all(color: Colors.blueGrey)),
          child: new Column(
            children: <Widget>[
              new FlutterLogo(size: 300.0),
              new Text('FSTM KUIS'),
              new Text('http://fstm.kuis.edu.my'),
              new Text('http://wasap.my/60129034614'),
              new RaisedButton(
                child: const Text('Connect our FB'),
                color: Theme.of(context).accentColor,
                elevation: 4.0,
                splashColor: Colors.blueAccent,
                onPressed: () {
                  // Perform some action
                },
              ),
              const Icon(Icons.sentiment_very_satisfied),

              new Row(
                children: <Widget>[
                  Mersing(),
                  Mersing(),

                ],
              )
            ],
          ),
        ),
      ),
    );
  }//end Widget
}//end class
