How to Determine Screen Height and Width

0 votes
I've created a new application on Flutter, and I've had problems with the screen sizes when switching between different devices.

I created the application using the Pixel 2XL screen size, and because I've had containers with a child of ListView it's asked me to include a height and width for the container.

So when I switch the device to a new device the container is too long and throws an error.

How can I go about making it so the application is optimized for all screens?

To optimize your Flutter application for different screen sizes, you can determine the height and width of the device's screen dynamically using the MediaQuery class.

Here's an example of how you can determine the screen size in your Flutter code:

import 'package:flutter/material.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final screenWidth = MediaQuery.of(context).size.width;
    final screenHeight = MediaQuery.of(context).size.height;

    return Container(
      width: screenWidth,
      height: screenHeight,
      // your child widgets here
    );
  }
}

By using MediaQuery.of(context).size.width and MediaQuery.of(context).size.height, you can get the screen width and height of the device your app is running on. You can then use these values to set the dimensions of your container dynamically.

Additionally, you can use the MediaQueryData class to get other device information, such as the device pixel ratio and orientation. This can be useful for making your app responsive to different devices.

Overall, using MediaQuery and MediaQueryData can help you create a responsive Flutter app that looks great on all devices.
