Flutterの環境構築をしてみた
2019.4.28
FlutterはDartでios/androidの両方のアプリを作れるフレームワークです。環境構築してみたのでその作業ログです。
基本的には公式サイトを参照しました。Flutterの公式ドキュメントはかなり充実していて、結構簡単に構築することができました。

FlutterのインストールからHello Worldまで
SDK取得
https://flutter.dev/docs/get-started/install/macos からsdkをダウンロード
インストール
cd ~/development
unzip ~/Downloads/flutter_macos_v1.2.1-stable.zip
.bash_profileに以下を追加(展開したファイルのflutter/binにPATHを通す)
export PATH="$PATH:`pwd`/flutter/bin"
Terminalを再起動してflutterコマンドがあることを確認。

flutter doctorというコマンドで必要なモジュールなどを教えてくれる。
$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.2.1, on Mac OS X 10.14.4 18E226, locale ja-JP)
[✗] Android toolchain - develop for Android devices
✗ Unable to locate Android SDK.
Install Android Studio from: https://developer.android.com/studio/index.html
On first launch it will assist you in installing the Android SDK components.
(or visit https://flutter.io/setup/#android-setup for detailed instructions).
If Android SDK has been installed to a custom location, set ANDROID_HOME to that location.
You may also want to add it to your PATH environment variable.
[!] iOS toolchain - develop for iOS devices (Xcode 10.2.1)
✗ libimobiledevice and ideviceinstaller are not installed. To install with Brew, run:

brew install --HEAD usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice

プロジェクトの作成
こちらのページを参考にしてプロジェクトを作成しました。VSCodeを使用しています。
https://flutter.dev/docs/get-started/test-drive?tab=vscode
初期プロジェクトのビルド
VSCodeにFlutterプラグインをインストール。VSCode上でF5キーを押すとデバッグが始まります。ios simulatorが起動し、HelloWorld的なアプリが起動します。
