Notes on running Flutter on a physical Android 10 device from macOS Catalina

This is a topic that has already been covered everywhere, but I'm making a note of it since I got a bit stuck.

1. Enable Android Developer Mode

Go to the "Settings" app -> Device information (near the bottom) -> Tap "Build number" (at the very bottom) 7 times.
As mentioned in the reference, it feels like an old-school cheat code.

2. Enable Android USB Debugging

Go to the "Settings" app -> System -> Open "Advanced" -> Open "Developer options"
-> Turn on "USB debugging"

When asked "Allow USB debugging?", tap OK.

3. Connect to Mac

Connect with a USB cable.
It's convenient that Mac and Android can now be connected via USB-C to USB-C.

4. Allow USB File Transfer from Android Notification Center

Open the notification center, tap "Charging via USB"
-> From advanced settings, select "Use USB for: File Transfer"

5. Check with flutter devices

Run flutter devices and if the connected device is displayed, the preparation is complete

6. Run flutter run

Execute flutter run

Some articles suggest that Android File Transfer is necessary, but it is not required.
