Flutter project when run showing Error Invalid argument(s): The source must not be null

I'm new to flutter. I created a simple flutter project when I trying to run. I was getting this error Unexpected failure from adb: Invalid argument(s): The source must not be null

Error launching the application on emulator-5554 This is my simple flutter application code:

import `package:flutter/material.dart`;
 void main(){
    runApp(
       new Center(
        child: new Text(
          "hello, world",
           textDirection: TextDirection.ltr,
        )
       )
    );
 }

Can anyone suggest me what might be the issue? How should I have to fix it?

When you connect the phone, there is options like USB Tethering, MIDI, PTP, file transfer etc... Choose PTP. If it doesn't work try MIDI. It will work.
