This is simple wrap your Expanded widget with stack and add the image widget as a first child to the stack.

Scaffold(
    appBar: AppBar(
      title: const Text('Sample UI'),
    ),
    body: Stack(
      children: [
        SizedBox.expand(
          child: Image.network(
            'https://images.pexels.com/photos/1624496/pexels-photo-1624496.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=1',
            fit: BoxFit.cover,
          ),
        ),
        SingleChildScrollView(
          child: Column(
            children: List.generate(100,(index) => 
                Text(
                  'Hello welcome $index',
                   style: const TextStyle(
                      fontSize: 20,
                      color: Colors.amberAccent,
                      fontWeight: FontWeight.bold,
                   ),
                )
             ),
          ),
        )
      ],
    ),
  )
