Flutter Frenzy: A Fun Way to Learn Flutter Development

Learning Flutter can be exciting, but it can also come with its fair share of challenges! Whether you’re just starting or looking to sharpen your skills, these challenges are designed to guide you through different stages of Flutter development. From setting up your environment to creating advanced apps, each challenge offers a unique opportunity to learn and grow.

There will be two version of the challenge for this week, one for those who want to go full in depth and download and set up Flutter, and those who want a more casual approach and use Dartpad.

FlutterSDK Challenge

The Setup Challenge - 100 Points

Download and Setup Flutter with Android Studio

The first and most important step in getting started with Flutter is setting up the environment. This is a crucial challenge that earns you 100 points right off the bat.

What You’ll Need:

  • Flutter SDK: Download the latest stable version of Flutter from flutter.dev.
  • Android Studio: Install Android Studio, which will provide the necessary tools to build and run your Flutter applications.

The Process:

  1. Install Flutter:
    • Follow the installation instructions on Flutter’s official website based on your operating system (macOS, Windows, or Linux).
  2. Install Android Studio:
    • Go to Android Studio and download the IDE.
    • During installation, make sure to select the Flutter and Dart plugins.
  3. Set Up Android Emulator:
    • Inside Android Studio, set up an emulator (virtual Android device) for testing Flutter apps.
  4. Verify Your Installation:
    • Run the command flutter doctor to check if everything is set up properly. If there are issues, the output will help you troubleshoot them.

Once you’re up and running, you’ll have 100 points for completing the setup!

  • Add a button to append new tasks to a list.
  • Display tasks in a scrollable list format.

Dartpad

Base Challenge for Flutter Development - 100 Points

If you prefer an online platform, don’t worry—DartPad is here to help! It’s an online editor that lets you try out Flutter code without needing to install anything on your computer.

DartPad: https://dartpad.dev/

DartPad is an excellent way to start learning Flutter if you don’t want to deal with the setup. To begin, you’ll tackle a simple Flutter challenge to create a basic app. This earns you 100 points.

Challenge 1: Create a Simple “Hello, Flutter!” App

  1. Open DartPad and select “Flutter” from the menu.

  3. Customize the app with some basic styling (e.g., change the text color, font size, and background color).
  4. Test your code by running it on the provided emulator.

Once you successfully complete this task, 100 points are yours!
