M1 ProのマシンでFlutter開発環境を準備する
11月にNew MBPを手に入れてFlutter開発環境を整えたものの、Kernel Panic発生により入院、初期化となりました😇
MBPが帰ってきたので再整備しようとしたところエラーが起きたのでメモ📝
Flutter
公式を参考にSDKを入手します。
https://docs.flutter.dev/get-started/install/macos
flutter doctor で確認
$ flutter doctor

║ Welcome to Flutter! - https://flutter.dev ║
║ ║
║ The Flutter tool uses Google Analytics to anonymously report feature usage ║
║ statistics and basic crash reports. This data is used to help improve ║
║ Flutter tools over time. ║
║ ║
║ Flutter tool analytics are not sent on the very first run. To disable ║
║ reporting, type 'flutter config --no-analytics'. To display the current ║
║ setting, type 'flutter config'. If you opt out of analytics, an opt-out ║
║ event will be sent, and then no further information will be sent by the ║
║ Flutter tool. ║

║ Moreover, Flutter includes the Dart SDK, which may send usage metrics and ║

何やらいろいろ出ています。
Android Studio & toolchain
こちらも普通に公式からDL. ARM版が用意されている。
android-studio-2020.3.1.26-mac_arm.dmg
Download Android Studio and SDK tools | Android Developers
11月に試した時はRC版でないとSDKのDLがされなかった記憶がありますが、12月時点では大丈夫そうです。
Android toolchain
コマンドラインからインストールできるようですが、今回はポチポチ入れてみました。
More Actions から、 SDK Manager を選択。
Android SDK Command-line Tools にチェックを入れてインストールします。
再度 flutter doctor を実行すると、 licenses not accepted の表示に変わりました。
[!] Android toolchain - develop for Android devices (Android SDK version 32.0.0)
! Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses
ここは指示どおりに flutter doctor --android-licenses を実行。
[✓] Android toolchain - develop for Android devices (Android SDK version 32.0.0)
Xcodeは AppStore からインストールしていました。
残った cocoapods は CocoaPods Guides - Getting Started を参照せよとのこと。そして公式の指示どおりにインストール。
sudo gem install cocoapods
再度 flutter doctor を実行。ここまでで、この状態。
$ flutter doctor

IntelliJ IDEA
IntelliJは普段使いしているので、別途インストール済みでしたが、これが何やら怒られています。 既にIssueが上がっていました。まだ直っていない様子。
IntelliJ 2021.2 だと動くというコメントがありました。手元の IntelliJ は 2021.3 だったので、一時的にDowngradeすることにしました。
https://www.jetbrains.com/toolbox-app/ から Toolbox を手に入れると、過去のバージョンを簡単に入手できます。
2021.2 をインストールして、再度 flutter doctor を実行。

無事、環境を復活させることができました。
