fvm flutter run No supported devices connected.

The "No supported devices connected" error occurs when no viable device is connected to the computer.

To solve this issue, you can follow these steps:

1. Connect a physical device to your computer using a USB cable, or launch an emulator.

2. Ensure that your device is properly connected and recognized by your computer.

3. Open a terminal or command prompt and navigate to your project's directory.

4. Run the flutter doctor command to check if Flutter recognizes your device. If not, follow the instructions provided by Flutter to set up your device.

5. Once your device is recognized, run the flutter run command again. This time, it should detect your device and launch the application on it.

If the issue still persists, make sure you have enabled USB debugging on your device. This option can usually be found in the developer options.

If you are using an emulator, you can try restarting the emulator or creating a new one using the AVD Manager.

Remember to make sure you have the necessary drivers installed and that your computer and device are properly connected.
