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

Step 1: Setup Flutter and FlutterFlow

Before you proceed to creating a custom loading screen for your FlutterFlow app, make sure you have Flutter SDK and FlutterFlow installed on your local machine.

• To install Flutter, follow the Flutter installation guide on the official Flutter website.
• For FlutterFlow, you don't need to install anything as it's a web-based tool. Just make sure you have an account. To create an account, go to the FlutterFlow website and sign up.

Step 2: Create a New Project

After setting up Flutter and signing up for FlutterFlow, you’re now ready to create a new project:

• Log into your FlutterFlow account.
• Click on the Create New button. A new window will appear on your screen.
• Enter the name of your new app project.
• Click the Create button to create a new FlutterFlow project.

Step 3: Build your App Screens

Now, you need to build your main app screens:

• On the FlutterFlow dashboard, click on your newly created project. This should open the FlutterFlow builder.
• Click on the + button shown at the left side of the builder to add a new screen.
• You can rename this new screen to Home Screen by double-clicking on the screen name.
• Repeat the above process and add another screen and name it Loading Screen.

Step 4: Design your Loading Screen

Design your custom loading screen:

• In the app's navigation tree on the left, click the Loading Screen you created in the previous step.
• Click on the + button at the top of the page, a dropdown menu will appear.
• From the dropdown, select Row under the Layouts group. This will add a new row to the middle of your loading screen.
• Click on the + button inside the row you just created and select Text from the dropdown under the Inputs group. This will add a text widget to your row.
• Click the widget to select it, a properties side window will appear on the right.
• In the properties side window, replace the current text in the Text field with the loading message you like, for example "Please wait, loading..."

Step 5: Add Animation to your Loading Screen

To make your loading screen more appealing, you can add animation:

• Click on the row you added to your loading screen.
• In the properties side window, scroll down and find the Animations field.
• Click the + button next to it, a new window will appear.
• From the Choose Animation dropdown, select the animation you like, for example "Spin".
• Click Add Animation button to add the animation.

Step 6: Implement the Loading Screen Logic

Implement the loading screen in your app:

• Navigate back to your project builder.
• On the left navigation tree, find and click on the Navigation group.
• In the Initial Page dropdown, select your Loading Screen.
• Below the dropdown, click the + button to add a new action.
• In the new action dropout, select Navigate to and in the page dropdown select your Home Screen.
• Set a duration for your action, for example 5 seconds. This will make your app wait 5 seconds on the loading screen before moving to the home screen.

Step 7: Test and Export your App

Now, you need to test your app and export it:

• At the top of the builder, click the Preview button to test your app. It should first show your Loading Screen with the animation, then after 5 seconds switch to the Home Screen.
• If the app operates as expected, click the Export button at the top right of the builder.
• A dialog will appear asking you to select the desired platform. Select and confirm your choice, and FlutterFlow will generate your app code.
• Download and use the generated code in your local Flutter development.

And voila! You have successfully created a custom loading screen for your FlutterFlow app.
