This is my first post on programming I hope you find it useful. As such I decided to create one and I’ll be sharing it with you here since it seems useful and I hope to improve and learn from you.īut before that I would like to hear your input on possible ways to improve. While there are loads of widgets to create drawers in Flutter, I couldn't find any that allowed me to easily expand and collapse a dual pane screen, with one pane for details and one for the main content.
I'll also be adding a few extra perks such as vertical layout, dual screen support, transition animations, etc. I'm thinking of creating a package with this so I want to optimize the code as much as possible. You can find the code for the example above and all the steps on github. Basically, the only change is that we are passing a list of items to pane1 and a detail card to pane2 A more realistic example would be something like the example below.
While what we've built works, it's not a very realistic use case. The first part is quite easy to do in flutter using a Flex widget, To make it easily reusable we will create a widget that holds and is responsible for the panes behaviour:Ĭlass TwoPane extends StatefulWidget Įnter fullscreen mode Exit fullscreen mode With that out of the way let’s get started. Close popup when window resized from small to big.When window is resized from big to small open popup if pane2 has content.Open a popup to show the 2nd pane content on small screens.Two panes for big screens and one for small screens.It should split into two panes when on large screens on small screens it should show only one pane and open a popup for the second pane as needed: In a nutshell, we want a widget that updates how the children are displayed depending on the screen size of the Window. This will help us focus on the task and keep track of our progress as we go along.
Responsive columns in flutter how to#
In this tutorial I will show you how to create exactly that.īefore we start coding let's define exactly what we want to achieve and tackle each part in incremental steps.
Multiple column layouts on large screens that collapse to drawers or popup's on small screens are extremely common on responsive apps.
