[Flutter]开发记录

1.官网:https://flutter.io/setup-macos/#system-requirements

2.准备SDK:https://flutter.io/setup-macos/

3.Add the flutter tool to your path:[macOS]设置全局命令

 

open ~/.bash_profile

 

export PATH=[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin:$PATH

 

source ~/.bash_profile

 刷新profile

4.Deploy to iOS devices:

 

 

brew update
$ brew install --HEAD libimobiledevice
$ brew install ideviceinstaller ios-deploy cocoapods
$ pod setup

 brew doctor可以看到错误和建议

 

5.Android studio 安装dart & flutter插件.先安装dart,要不可能报错

 

5.flutter doctor检查

补充完插件\IDE等等

 

6.Android studio new file->new flutter project

 

7.Use an external package

 In pubspec.yaml, add english_words (3.1.0 or higher) to the dependencies list. Add the highlighted line below:

 

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.0
  english_words: ^3.1.0

 While viewing the pubspec in Android Studio’s editor view, click Packages get.

 

 

In lib/main.dart, import the new package:

 

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final wordPair = WordPair.random();
    return MaterialApp(
      title: 'Welcome to Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Welcome to Flutter'),
        ),
        body: Center(
          //child: Text('Hello World'), // Replace the highlighted text...
          child: Text(wordPair.asPascalCase),  // With this highlighted text.
        ),
      ),
    );
  }
}
