How to create a custom error screen for your FlutterFlow app?

Step 1: Create a new FlutterFlow project

Login to your FlutterFlow account. If you don't already have one, sign up at https://flutterflow.io/.

After successfully login, create a new project by clicking the +New Project button in the upper left corner of the dashboard.

Step 2: Create a new custom screen

When your project is successfully created, proceed to the front-end design interface of the FlutterFlow Builder. At the top-sidebar, click on the Screen tab to add a new screen.

Next, click the + button on the sidebar to add a new screen. Name your screen something like 'ErrorScreen'.

Step 3: Design the Error Screen

With the new screen created, you can begin to design your custom error screen. First, let's add a label to display the error message. You can do this by clicking on the +Add Widget button on the sidebar and selecting the Label widget.

In the properties panel for the label, customize the following properties:

• Enter your error text into the Text input field.
• Adjust the Text Color to something that matches your app's branding.
• If you want, you can customize the Font Family, Font Size, and alignment of the text.

Also, add a Button using the +Add Widget and customize it as well to return to the home screen.

Step 4: Add Logic to the 'Return Home' Button

Once you've added the button, click on it to open the properties panel. Here, you will find the options to customize the appearance of the button.

After customizing, proceed to the Actions tab in the properties panel. Click the +Add Action button and click on the Navigate action. In the 'To' field, select the home screen or any other screen you would like the user to navigate to when they press the button.

Step 5: Set the Error Screen as the Default Error Screen

To set this newly designed screen as your default error screen, navigate back to the main sidebar and click on the Settings tab.

Scroll down to the Error Screens section. You will see the option to set the default error screen for different types of errors, such as 404 errors or Firebase errors. Choose your newly created 'ErrorScreen' as the default for these errors.

Step 6: Save and Deploy Your Project

After configuring your settings, click the Save icon located at the top right of the FlutterFlow interface. Then, you can deploy your project by clicking the Deploy button.

Congratulations! You've successfully created a custom error screen for your FlutterFlow app. When users encounter an error in your app, they will be directed to this custom-designed error screen.
