What is an SDK ?
A software development kit (SDK or devkit) is typically a set of software development tools that allows the creation of applications for a certain software package, software framework, hardware platform, computer system, video game console, operating system, or similar development platform.
What is a Framework ?
A framework, or software framework, is a platform for developing software application. It provides a foundation on which software developers can build programs for a specific platform.
Why do we need uniformity ?
Uniformity is generally required these days because most applications are released for both platforms android and iOS and this means, if a company is taking a native approach to build both apps a lot of money would be spent on development.
What is Flutter ?
Flutter is a free and open-source software development kit (SDK) launched by Google to create mobile apps for iOS, Android, and Google Fuchsia. Its framework is based on reactive programming which incorporates Dart programming language, ready-made widgets, et al. The Google’s development kit enables users with building 2D mobile apps.
Flutter is a cross-development framework that helps users in building fully-equipped apps supporting cameras, storage, network, geolocation and so on. The framework facilitates app development for Android and iOS from a single database and the programmers can do more with less code.
One for all and all for one :
Flutter allows developers to create native application for both iOS and android using one codebase, while also giving room for optimization based on the platform being targeted in the development cycle. This saves time in learning two different languages and lot of money too.
Easy Learning curve :
Flutter has easy learning curve. Anybody having experience with objected oriented programming will find it extremely easy to learn flutter. Even if you are a beginner who is just starting his career in mobile development , flutter is still very easy to learn and implement.
Improve your resume :
Flutter is new and trending. If somebody is hiring for a developer, and looks at flutter in your resume he knows you can develop apps for both platform and its going to save the company a lot of money. This only makes your resume more lucrative and provides a higher chance at getting hired.
Flutter Architecture :
The Widget Tree :
An application built using flutter is designed using widgets. Everything is a widget. So the entire application becomes a tree of widgets. Some widgets are just for layout precision while others for visual enhancement.
Embrace platform difference :
Flutter is amazing as it embraces the difference between the platforms, iOS and android differently for how services API's are called and handled. Flutter embraces these differences gracefully giving the developer complete control over the application and its behaviours.
Type of Widget :
Stateful Widget : This is a widget that can be changed dynamically. Sateful widget are mutable and can be drawn multiple times within its lifetime.
Stateless Widget : Stateless widget are immutable once built. To redraw a stateless widget, A new instance must be created.
