Pada saat instalasi Flutter & menjalankan flutter doctor terdapat eror sbb:
softwareengineeringprasmul@Softwares-MacBook-Pro % flutter doctor Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel stable, 1.22.5, on Mac OS X 10.15.5 19F101 darwin-x64, locale en-ID) [✓] Android toolchain - develop for Android devices (Android SDK version 30.0.2) [✓] Xcode - develop for iOS and macOS (Xcode 12.1) [!] Android Studio (version 4.1) ✗ Flutter plugin not installed; this adds Flutter specific functionality. ✗ Dart plugin not installed; this adds Dart specific functionality. [✓] VS Code (version 1.52.0) [!] Connected device ! No devices available
Solusi:
Pastikan Anda sudah menginstal extension Flutter pada Android Studio

Kemudian, ketik command berikut pada terminal:
ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1
Setelah itu, ketik kembali flutter doctor pada terminal:
