About the test

The Flutter online test assesses knowledge of key concepts used to build UIs with Flutter, through a series of multiple-choice and fill-in-the-blank questions.

The assessment includes work-sample tasks such as:

  • Managing and configuring widgets.
  • Navigating between routes.
  • Using conditional rendering to dynamically show/hide UI elements.

A good Flutter developer should be able to work with the Flutter framework to build high performance and user-friendly interfaces.

You are making a Flutter widget to display a popup ad in your app.

The popup ad has 3 sections - title, main, and footer.

Below is the code of the widget:

    crossAxisAlignment: CrossAxisAlignment.center,
    mainAxisAlignment: MainAxisAlignment.spaceBetween,
    children: <Widget>[
        flex: 2,
        child: Container(
          margin: EdgeInsets.symmetric(vertical: 5),
          width: double.infinity,
          child: Center(child: Text("Title content"))),
        flex: 4,
        child: Container(
          width: double.infinity,
          child: Center(child: Text("Main content"))),
        flex: 1,
        child: Container(
          width: double.infinity,
          child: Text("Footer content"))

What can we conclude about the layout of the above widget?

Life Cycle

A voting application made with Flutter uses the VoteOnce widget, which allows the user to trigger the onTapCallback function only once no matter how many times it's tapped.

The code for VoteOnce widget is given below:

class VoteOnce extends StatefulWidget {
  final Function onTapCallback;
  final String tapText;

  const VoteOnce({Key? key, required this.onTapCallback, required this.tapText}): super(key: key);

  _VoteOnceState createState() => _VoteOnceState();

class _VoteOnceState extends State<VoteOnce> {
  bool _wasTapped = false;
  String _displayText = "";

  void initState() {
    _displayText = widget.tapText;

  Widget build(BuildContext context) {
    return Container(
      child: GestureDetector(
        onTap: () {
          if (!_wasTapped) {
          setState(() {
            _wasTapped = true;
            _displayText = "Voted";
        child: Text("Vote for $_displayText"),

What can be concluded about the lifecycle of the VoteOnce widget?

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
