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

Step 1: Setting up FlutterFlow

First, create a new FlutterFlow project. Navigate to the FlutterFlow homepage and click on the New Project button. Then, give your project a name that represents the quiz and click Create Project.

Step 2: Designing the Quiz Widget

Click on the Add Widget button located at the top right corner of the screen. From the pop-up that opens, click on Create Custom Widget.

In the Create a new widget window that appears, fill in your widget's name (for instance, "Quiz"). Click OK to create the widget.

Step 3: Configuring Widget Properties

Within the widget creation interface, you will see four sections: Title, Inputs, Outputs, and Actions.

In the Title section, place the name "Quiz".

For the Inputs section, define the properties you'll need in your quiz, i.e., quiz questions, the right answers, and options. For each question, there should be four options namely A,B,C and D.

Under Outputs, you will have user's responses stored as UserResponse

Step 4: Designing the Layout

Next, drag and drop a Container to your widget from the Layout section. This widget controls the arrangement of its child widgets.

Inside the Container, add a Column widget, which allows placing several widgets vertically. Add a Text widget into the Column widget. This widget will display each question text.

For each question option, Add separate Radiogroup widgets for options A, B, C, and D. Attach respective Inputs for them and ensure they are selectable by the user. This will allow users to select one option for each question.

Step 5: Connecting Quiz Questions

Click on Bind on each Text and Radio Options. Bind each to the respective Input that you defined previously. This will ensure the text or options displays accurately.

Step 6: Implementing Logic

Every time a user selects an answer, you would like to compare it to the correct answer to update the score. FlutterFlow uses Actions for this.

Click on the small + button beneath your RadioGroup widget and click On Tap Event. Then, choose the If Else Action. With this, you can specify what should happen if a condition is met (if the user's answer is correct) or not (if the user's answer is incorrect).

If the answer is correct, increment a score variable, if not, do nothing.

Step 7: Displaying Score

After the user finishes the quiz, the score should be displayed, and you can allow them to reset the quiz. Add a Text widget beneath your RadioGroup widgets to display the score.

Then, add a Button widget at the end of the widget. Bind its On Tap action to reset all the RadioGroup widgets to their initial state.

Step 8: Save and Exit

Finally, click on Save to apply the changes to your widget and then exit the interface.

Congratulation! You've created a custom Quiz widget. You can now use this widget in your FlutterFlow app by dragging and dropping it into any of your apps' screens.

Remember, the key to creating successful FlutterFlow apps and widgets is to continually test your app and make improvements where necessary. Happy coding!
