What is Flutter? What it can do ?

Flutter is Google’s UI toolkit which build for natively development , building beautiful, reposive complined application for moblie , web and desktop. In simple word build with quote “ BUILD ONCE RUN AT EVERYWHERE”

Flutter Advantages:

Keep in flutter build by google so it’s performance is less when it comes to iOS device because of platform competition

For engineering managers and businesses, Flutter allows the unification of app developers into a single mobile, web, and desktop app team, building branded apps for multiple platforms out of a single codebase. Flutter speeds feature development and synchronizes release schedules across the entire customer base.

What programming Language used?

Dart its Language

Dart is client-optimized Language for fast apps on any platform. This was developed by google in 2011.Dart is fast on all platforms because its Complied to ARM & x64 machine code for moblie , desktop , and backend. Or complied to Javascript for web.

Dart is Syntax are simpler and similar to javascript so it will easy for people coming from javascript background.The Dart language is type safe; it uses static type checking to ensure that a variable’s value always matches the variable’s static type. Sometimes, this is referred to as sound typing. Although types are mandatory, type annotations are optional because of type inference. The Dart typing system is also flexible, allowing the use of a dynamic type combined with runtime checks, which can be useful during experimentation or for code that needs to be especially dynamic.

What is Widget?

you’ll be wondering what is Widget because I used it above !!! I get it flutter apps are build using widget.Flutter widgets are built using a modern framework that takes inspiration from React. The central idea is that you build your UI out of widgets. Widgets describe what their view should look like given their current configuration and state. When a widget’s state changes, the widget rebuilds its description, which the framework diffs against the previous description in order to determine the minimal changes needed in the underlying render tree to transition from one state to the next.

Basic widgets

Flutter comes with a suite of powerful basic widgets, of which the following are commonly used:

TextThe Text widget lets you create a run of styled text within your application.Row, ColumnThese flex widgets let you create flexible layouts in both the horizontal (Row) and vertical (Column) directions. The design of these objects is based on the web’s flexbox layout model.StackInstead of being linearly oriented (either horizontally or vertically), a Stack widget lets you place widgets on top of each other in paint order. You can then use the Positioned widget on children of a Stack to position them relative to the top, right, bottom, or left edge of the stack. Stacks are based on the web’s absolute positioning layout model.ContainerThe Container widget lets you create a rectangular visual element. A container can be decorated with a BoxDecoration, such as a background, a border, or a shadow. A Container can also have margins, padding, and constraints applied to its size. In addition, a Container can be transformed in three dimensional space using a matrix.


  1. Same Ui and Business Logic in ALL Platform
  2. Reduce Code Development Time
  3. Increased Time-to-Marked Speed
  4. Similar to Native App Preformance
  5. Custom ,Animated Ui of Any Complex Available
  6. Simple Platform-specific logic Implementation
  7. Own Rendering Engine
  8. The Potential Ability to Go Beyond mobile.

So Why Try Flutter?

Let’s briefly go through the most outstanding advantages of the framework:

What kinds of apps can I build with Flutter?

Flutter is designed to support mobile apps that run on both Android and iOS, as well as interactive apps that you want to run on your web pages or on the desktop. (Note that desktop support is in beta, but a snapshot of the beta is available on the stable channel.)

Apps that need to deliver highly branded designs are particularly well suited for Flutter. However, you can also create pixel-perfect experiences that match the Android and iOS design languages with Flutter.

Flutter’s package ecosystem supports a wide variety of hardware (such as camera, GPS, network, and storage) and services (such as payments, cloud storage, authentication, and ads).
