title: How to Determine Screen Height and Width
body: <p>I've created a new application on flutter, and I've had problems with the screen sizes when switching between different devices.</p>
  <p>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.</p>
  <p>So when I switch the device to a new device the container is too long and throws an error.</p>
  <p>How can I go about making it so the application is optimized for all screens?</p>
