ProKit is a handy toolkit for Flutter. With it, you can create a customized UI for your app with a few simple steps.
The first thing you need to do is download the app from the Google Play Store. Then, install it on your device and open the app. Now, you can start creating your custom UI.
To get a better idea of what you can do with the app, you can look at one of the templates that are already created. There, you can find all the elements that are part of the template.
Once you get the elements you want, you can combine them to create a new UI. You can choose to use any of the elements from the template and combine them as you see fit. You can edit any of the elements and even change the colors and fonts.
