How to create a custom bottom sheet for your FlutterFlow app?

Step 1: Setting Up FlutterFlow Environment

Before we proceed, it's imperative that you have FlutterFlow set up. This process requires creating an account and signing in. Upon completing that, you will be directed to the FlutterFlow project dashboard. Click 'Create New' to create a fresh project for the application.

Step 2: Define the structure of your Application

Next, you need to develop the structure of your application. To do this, click on the '+' (plus) symbol located at the left panel to create a new screen. Name it according to your preference, then click 'OK'.

Step 3: Design the Base Screen

Now, it's time to design the base screen where your bottom sheet will pop up. To this end, select Widgets from the left panel and drag the Container widget into the phone screen in the canvas area. Change the color, size, and shape as per your preferences.

Step 4: Addition of Button to Trigger Bottom Sheet

To provide user interaction with the bottom sheet, you must create an element that can trigger this action.

• In the Widgets section, find and drag the Button widget onto the base screen in the canvas.
• Set this button's OnClick Event properties to 'Show Custom Bottom Sheet'.
• In the 'Show Custom Bottom Sheet' field, you will be required to choose a widget. Since we haven't created it yet, leave it blank for now.

Step 5: Creation of Custom Bottom Sheet

After the base screen and triggering element has been set up, focus will now shift to the creation of the custom bottom sheet.

• On the left panel, click 'Create New Screen'.
• Name it accordingly ie. 'My Custom Bottom Sheet' and click 'OK'.
• On this new screen, you will design your custom bottom sheet.

Step 6: Designing the Custom Bottom Sheet

In this stage, the contents and layout of the bottom sheet must be defined. Drag and drop different widgets from the left panel to the screen canvas:

• Several commonly included components include Text, Buttons, Images, etc.
• Position them appropriately on the canvas, keeping in mind that this screen will pop up as a bottom sheet.
• Once satisfied with the layout and design, it's time to link it back to the base screen.

Step 7: Linking Custom Bottom Sheet to Base Screen

After creating the bottom sheet, it must be linked to the triggering element in the base screen.

• Go back to the base screen and select the button created in step 4.
• Under the OnClick Event field, find and select 'Show Custom Bottom Sheet'.
• In the drop-down menu revealed, find and select the custom bottom sheet created in previous steps.

Step 8: Save and Preview your Application

Once everything is set up, click on the 'Preview' button at the top of your FlutterFlow dashboard to preview your changes and make sure everything works as intended.

And there you have it! You've created a custom bottom sheet for your FlutterFlow App.

Remember that FlutterFlow offers the flexibility to keep trying different looks for your bottom sheet until you achieve the best result. So, feel free to experiment and iterate!
