Getting Started Beginning Flutter 3.0 With Dart
Before getting started, let me tell you one thing. Always use the latest Provider package – https://pub.dev/packages/provider1 for state management. And always maintain the Null Safety https://flutter.dev/docs/null-safety2.
I also strongly recommend to read the latest and updated articles on Flutter – https://sanjibsinha.com/category/flutter 3.
Download latest Flutter 3.0
To start with, we need to download the Flutter framework.
That is our first task. We need to go to The installation page of Flutter – https://flutter.dev/docs/get-started/install4 page from where we will download and install Flutter according to your operating system.
However, Flutter gets updated and upgraded quite often.
For example, Text Buttons to take inputs from users are no longer the same now. We will start with Windows, first. Want to read more old and archived Flutter related Articles and resources? For more old and archived Flutter related Articles and Resources5
Before that we want to make one thing clear.
What is new in Flutter 3.0
A few days ago Google announced the official release of Flutter 3.0. Let’s see what is new in Flutter 3. Firstly, with reference to mobile application development, there has not been a great change. Structurally what we have been doing, will continue to do. Certainly a change in here and there had taken place. In the next section we’ll discuss that and will take a deep dive.
Secondly, flutter web sections have got the makeover. Certainly it has become better. Finally, a lot of changes have taken place in the desktop part.
Three months ago Google Flutter and Dart team announced Flutter support for Windows.
Flutter 3.0 is stable for macOS and Linux.
With reference to macOS and Linux, a lot of changes have taken place.
Now it’s ready for production on all desktop platforms. As a result, we can now create platform- rendered menu bars on macOS. To do that we can use the “PlatformMenubar” widget that inserts platform-only menus.
It also supports accessibility services such as screen-readers, accessible navigation, and inverted colours. Full support for international text input on all desktop platforms is also there.
Web updates in flutter 3.0
Let’s talk about the Web updates in flutter 3.0.The “ImageDecoder” API plays an important role in web applications.
Therefore flutter web now uses the “ImageDecoder” API in browsers that support it. And there are more.
We can also use other widgets in flutter web. For example we can think of the splash screen, loading indicator etc. Most importantly, Flutter 3.0 has improved the performance. It is faster than before.
As an outcome it builds frames 20 percent faster which is a significant progress. Last but not least, we should mention two interesting things that have caught our attention. Firstly, Flutter 3.0 supports foldable mobile devices. Secondly, Flutter 3.0 supports Material Design 3. In the next section we’ll talk about it in detail.
Who should read this Beginning Flutter 3.0 With Dart book?
Are you an absolute beginner who without having any prior knowledge of programming language wants to build a mobile application? Well, then this book is for you. This Beginning Flutter 3.0 With Dart book is not for intermediate or experienced learners or developers.
We will try to add two things to our knowledge so that we will start building your mobile application. First we will learn Flutter, a framework or tool that helps us to build the mobile application. Second, we will learn a programming language called Dart, with which Flutter works.
If we do not understand the basic syntax and semantics of Dart, we will not be able to understand the internal activities of Flutter. We will learn both, Flutter and Dart side by side. For instance, if we find something like function and object or named parameters in a constructor, we will learn that concept in Dart.
If you have no knowledge of programming language, or you have not written a single line of code, you need not worry. We will go very smooth, we will have plenty of screenshots that will explain what we are going to do. We will also learn the basic concepts of programming language through Dart; it is important, because otherwise we will not be able to understand how Flutter framework works.
