Flutter app development is the process of creating mobile applications using the open-source framework, Flutter, developed by Google. Here's the gist:

• Single codebase for multiple platforms: Unlike traditional development where you write separate code for iOS and Android, Flutter allows you to build a single codebase and deploy it on both platforms (and even web, Windows, macOS, and Linux). This saves time and resources.

• Building with Widgets: Flutter uses widgets as building blocks for the app's user interface (UI). These widgets are like Lego bricks – you can combine them to create anything from simple buttons to complex layouts.

• Declarative approach: Instead of writing intricate code to control every aspect of the UI, Flutter uses a declarative approach. You simply describe what the UI should look like based on the current state of your app, and the framework takes care of rendering it efficiently and updating it as needed.

• Benefits: There are several advantages to using Flutter for app development, including:

  • Faster development with code reusability.
  • Cost-effective due to the single codebase approach.
  • Ability to create beautiful and smooth UIs.
  • Rich set of pre-built widgets and tools.

Flutter is an open-source framework that allows developers to build apps for various platforms, including iOS, Android, web, Windows, macOS, and Linux, using a single codebase. This means they write the code once, which can be deployed on these different platforms.

ross-platform development: This is the core advantage of Flutter. Instead of creating separate apps for iOS and Android (native development), developers can create a single app that works on both platforms with a single codebase. This saves time and resources.
