How to Properly Hide the FloatingActionButton When the EndDrawer is Open in Flutter

Flutter allows developers to build beautiful applications with ease, but sometimes managing various UI elements can be tricky. A common challenge new Flutter developers face is how to hide the FloatingActionButton (FAB) when the endDrawer is open. In this guide, we will address this problem and provide you with workable solutions, step-by-step.

The Problem

You may have a scenario where your app includes two drawers: a left drawer and an end drawer (right drawer). You might notice that while you can already hide the FloatingActionButton on scroll, you still want it to disappear when the endDrawer is opened, whether by pulling it open or by selecting an item from the app bar.

Why is the FloatingActionButton Still Visible?

The core of the issue lies in the positioning of your FloatingActionButton and endDrawer. If the FloatingActionButton is layered above the child Scaffold (which contains the end drawer), it won't automatically be hidden when the end drawer is opened.

Solution Overview

To solve this issue, you'll want to consider the following options, either adjusting the structure of your Scaffold or moving the FloatingActionButton to the correct layer.

Option 1: Move the EndDrawer to the Parent Scaffold

One effective solution is to move the endDrawer to the parent Scaffold. By doing so, the FloatingActionButton will be aware of the drawer's state and can hide itself accordingly. Here's a sample code for clarity:

Option 2: Move the FloatingActionButton to the Child Scaffold

Alternatively, you can also consider adjusting where the FloatingActionButton resides. Moving the FloatingActionButton into the child Scaffold might solve the visibility issue without needing to rearrange your Scaffold structure completely.

Here's how you could structure this approach:

Conclusion

In this guide, we tackled the issue of hiding the FloatingActionButton in Flutter when the endDrawer is open. Remember that the placement of the FloatingActionButton and endDrawer is crucial for proper functionality. By moving the drawers into the correct Scaffold, or by positioning the FloatingActionButton appropriately, you can create a more intuitive user experience in your Flutter applications.

Make sure to test both options to see which one works best for your specific app setup, and happy coding!
