        appBar:AppBar(
          title: Text("I am rich"),
              backgroundColor: Colors.blueGrey[900],

  // ignore: prefer_const_constructors

You are missing a "," at your AppBar

    appBar:AppBar(
      title: Text("I am rich"),
          backgroundColor: Colors.blueGrey[900],
    ), // This comma is missing

In analysis_options.yaml you can add require_trailing_commas: true (experimental) to your linter options, this will force you to use comma's everywhere and will make your code more legible in the long run.

Your Answer is

void main() {
  runApp(
    MaterialApp(
      home:Scaffold(
        backgroundColor: Colors.blueGrey,
        appBar:AppBar(
          title: Text("I am rich"),
              backgroundColor: Colors.blueGrey[900],
        ),
      // ignore: prefer_const_constructors
      body: Image(
          image: NetworkImage('https://www.publicdomainpictures.net/pictures/320000/velka/background-image.png')

      )
      ),
    ),
  );
}

Just Copy And Paste The Code That I Have Added
