![]() I therefore did add some helper functions that I can use instead of MediaQuery.of(context).size. because it doesn't take the maxWidth of the ConstrainedBox as the device width. For min width and height you then need some kind of scrolling for small screens, but that's probably already out of the scope of the question □Įdit: You have to be careful with this solution while using MediaQuery.of(context).size. ![]() You can easily implement functional widgets like AppBar, FloatingActionButton, ButtonNavigationBar, Drawer, and many more widgets on the app using the Scaffold widget. ![]() It is used to implement the basic functional layout structure of an app. You could obviously change for exmaple the alignment if you want the page to always be in the upper left corner, the color of the background and the max and min width and height. Navigation & Routing Flutter AppBar The Scaffold widget is the base of the screen for a single page. The inner box also could be a ConstrainedBox, that probably would be a little bit better for readability: Container( double width MediaQuery.of (context).size.width // Gives the width double height MediaQuery.of (context).size. We can calculate the screen height and width using MediaQuery. The outer one has to be the 'background' container which sets the background color and has alignment set to Alignment.center and the inner container has to be the constrained one with for example constraints: BoxConstraints(maxWidth: 1000).Ĭonstraints: const BoxConstraints(maxWidth: 1000), Flutter gives us to make a responsive screen by calculating screen size. The best working solution I found was to put the MaterialApp or the Scaffold itself into two Containers. Properties of Container widget Container( color: een, constraints: BoxConstraints.tight(Size size) : minWidth size.width, maxWidth size.width. I didn't find a good working example for that problem, so I tried a few things myself.
