How to Create a Sliding Up Panel in Flutter with a Button Click

Flutter is an incredibly powerful UI toolkit that allows developers to build stunning and responsive applications for mobile, web, and desktop. One common UI pattern in mobile applications is the sliding panel, a great way to add additional information or controls without overwhelming the user interface. In this guide, we will explore how to implement a Sliding Up Panel in Flutter, which opens up when the user taps a button.

Understanding the Scenario

You may want to implement a feature in your app where a panel is hidden and only becomes visible when the user clicks a button. This can enhance user experience by keeping the interface clean and engaging.

The Main Components

For our solution, we will be using the sliding_up_panel package, which makes it easy to add this functionality to your Flutter app. We will define a sliding panel that can be opened and closed based on user interaction.

Step-by-Step Guide to Implementing Sliding Up Panel

Step 1: Add the Dependency

First, make sure you have the sliding_up_panel package added in your pubspec.yaml file:

Step 3: Implement the Main Home Page

Now we will create our main page, MyHomePage.dart. This page will have a button that triggers the sliding panel to open.

Here’s how to implement it:

Key Points to Remember

Initial Panel State: Set the defaultPanelState to PanelState.CLOSED to have the panel start off hidden.

Open Panel Function: Utilize panelController.open() to open the panel when the button is tapped.

Customization: You can easily customize the content inside the panel by modifying the Panel widget.

Conclusion

By following the steps outlined in this guide, you have successfully created a Sliding Up Panel in your Flutter application that opens when a button is clicked. This feature not only keeps your app interface clean but also improves user engagement.

Feel free to customize and adapt this code to fit your specific application needs!
