How to create a custom survey widget for your FlutterFlow app?

In this detailed tutorial, we are going to walk through the steps needed to create a custom survey widget for your FlutterFlow app. Before you start, ensure that you have Flutter SDK and an IDE like VS Code or Android Studio installed.

Step 1: Create New FlutterFlow Project

Initiate this process by creating a new FlutterFlow project. On your FlutterFlow dashboard, click on the + New Project button at the top right corner. Give your new project a name and click on Create.

Step 2: Add a New Blank Screen

Once your new project is created, you'll be redirected to the canvas. On the canvas, click + Add and select Blank. A new blank screen is added to your app design.

Step 3: Create a Container for the Survey Widget

Back in the canvas, search for Container in the Widgets menu, then drag and drop it onto the blank screen. You need to adjust the container size according to your preferences using the Width and Height options on the right.

Step 4: Create Your Survey Question Text

Next, you need to create your survey question text. Find a Text widget in the Widgets menu, then drag and drop it inside your container. Adjust the text properties to suit your taste. Use the properties panel on the right to adjust the font size, color, style, and more.

Type your survey question inside the Text Value input.

Step 5: Adding Answer Options

To add answer options, search for the RadioButton or Checkbox widget in the Widgets menu, depending on whether you need single or multiple answer options respectively. Drag and drop your chosen widget below the Text widget inside the container.

Create extra answer options by adding more RadioButton or Checkbox widgets as needed.

Step 6: Configure Actions for Answer Options

With each RadioButton or Checkbox widget you added, you need to configure actions when an option is selected. Click on each RadioButton or Checkbox widget, go to the Actions tab and set an action. The action could be saving the answer to a variable, directing the user to another screen, etc.

Step 7: Adding More Survey Questions

To add more survey questions, repeat Steps 4 to 6. Each new question should be contained within a new Container widget for better layout and control.

Step 8: Creating Survey Submit Button

Finally, you need a submit button for your survey. Locate the Button widget in the Widgets menu, then drag and drop it below the last survey question.

Customize the button properties (such as text, color, size, etc.) according to your requirement. Set an action for the button like sending the answers to a server, showing a results screen, etc.

Step 9: Review and Publish

After you finished creating your custom survey widget, it is advisable to review and conduct some tests to ensure everything works perfectly.

Navigate to the top right corner of the canvas and click on the Preview button to preview the survey. Confirm that all the survey questions and answer options are displaying correctly and the actions are being triggered as expected.

You can then click on the Publish button to deploy your app with the custom survey widget.

Step 10: Implement Changes in Your Flutter Code

The very last step is to implement the changes in your Flutter code. Download the project from FlutterFlow and import it into your IDE.

In the lib folder, find the dart file corresponding to your survey screen. In the build method, you'll see the Flutter code for your custom survey widget. Now you can use this survey widget anywhere in your Flutter app.

And there you go! By following these steps, you've learned how to create a custom survey widget for your FlutterFlow app. Now you are more capable of customizing your app according to your requirements. Happy coding!
