Try this.

import 'package:flutter/material.dart';

class Amd extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(
        image: DecorationImage(
          image: NetworkImage("Image Address"),
        ),
      ),
      constraints: BoxConstraints(
        maxWidth: 100,
        maxHeight: 200,
      ),
    );
  }
}


Solution 2: Philip Dolenko

Try wrapping your Image.network into Container with specific height & width or set constraints as UTKARSH Sharma proposed


Solution 3: Viren V Varasadiya

You can use Flexible Widget.

    Flexible(
              child: Image.network(
                "http://rcwebsitecss.gbfine.com/Mobile_SportsII/images/logo/display_logo_007.png",
                fit: BoxFit.fitWidth,
              ),
            ),
