10 Flutter Interview Questions You Can Expect

Flutter has spawned a new breed of software developers known as Flutter Developers since its official release in 2018. Developers can use Flutter to create cross-platform applications. Thus, it is not such a stretch to say that the demand for Flutter Developers will continue to rise shortly.

Although opportunities are soon to open, it is another thing to seal the deal. This blog will highlight ten Flutter Developer interview questions and how one might be able to answer them.

Common Flutter Interview Questions and Answers

Flutter developer interview questions get categorized into two:

  • Written Questions: These flutter interview questions for experienced and non-experienced developers mostly test the knowledge of Dart Programming Language.
  • Verbal Questions: These interview questions for Flutter developers test knowledge on the Flutter framework. They may also include questions on the Dart programming language.

Here are ten examples of the most commonly asked Flutter Interview Questions and Answers to help you seal the deal:

  1. What is Flutter?

Flutter is a user interface toolkit for building natively built mobile apps using a single programming language and codebase. It is a Google-developed open-source development framework, not a programming language. On the other hand, the Dart programming language gets used to create Flutter apps.

  1. What is Dart?

Dart is an open-source, C-style object-oriented programming language with a general-purpose syntax created by Google in 2011. Moreover, Dart programming is used to construct front-end user interfaces for online and mobile applications and is crucial for developing Flutter apps. Dart can compile both AOT (Ahead-of-Time) and JIT (Just-in-Time).

  1. What are the Flutter Widgets?

A Flutter app gets thought of as a collection of widgets. Widgets indicate how the current setup and status of your program should appear. When you modify the code, the widget regenerates its description by calculating the difference between previous and current widgets to identify the smallest adjustments needed for app UI rendering.

  1. What are the Best Editors for Flutter Development?

The Flutter development tools make Flutter development faster, allowing developers to work more efficiently. The Flutter IDE and tools require specific plugins. The following are some of the most popular IDEs for Flutter development to design mobile applications:

  • Android Studio
  • IntelliJ IDEA
  • Visual Studio
  • Xcode
  1. What are Packages and Plugins in Flutter?

There is not much of a difference between packages and plugins. Plugins offer greater functionality on the device by using native code, whereas packages are new components or code written in different languages. It is possible to import new widgets or functionality into a Flutter app.

  1.  Why does the first Flutter App build Take so Long?

It will take longer to construct the Flutter app for the first time. This length of time is because Flutter created the device-specific APK or IPA file. As a result, the file gets built using Gradle and Xcode, which naturally takes longer.

  1. Explain Hot Reload in Flutter.

The hot reload feature allows you to execute an experiment in the project quickly and efficiently. It aids in creating user interfaces, the addition of new features, the correction of bugs, and the rapid development of apps.

  1. Name some Popular Apps that use Flutter.

Many companies now use Flutter to create their apps. The following are some of the most popular Flutter apps:

  • Alibaba
  • Birch Finance
  • Google Ads
  • Reflectly
  • Watermaniac
  • XWalk
  1. Which type of Animation allows you to Represent Real-world Behavior?

Flutter’s physics-based animation lets you represent real-world behavior.

  1.  What are the Advantages of Flutter?

The following are some of the most well-known benefits of the Flutter framework:

  • Cross-platform Development
  • Documentation
  • Faster Development
  • Live and Hot Reloading
  • UI Focused


Flutter development is a fascinating area to explore. With a huge amount of potential, the demand for Flutter developers should skyrocket in the future.
