A tutorial for Flutter App Development including tips and tricks

Flutter is the recent launch that is in the news for quite some time now and all of the people are very excited about the launch as well. The non-game applications must make a smooth transition to the flutter and hence the team of flutter app development are getting hands-on training on the same. 

Tutorial for flutter app development:

1. What, why and how- Flutter

In a Flutter app development company in USA and being a flutter app developer, you have to know one thing that it is something that will run in any device that has a screen like for example- it works on iOS and android. Web like Ubuntu, Mac and Windows. 

2. Set up the flutter

It is very easy to set up and depend on the OS. Before Dart, you have to setup Flutter because if you install Flutter then you have to install Dart. You can install Dart separately but it will not become any necessary step.

3. Dart Basics

Flutter takes the help of dart language in the building of the apps. Both Chrome and Flutter will use SKIA engine. It does not interact with native APIs you will get control of the pixel in the screen and it will give all the necessary freedom the baggage of legacy with proper performance. Before you create the app, you have to learn the dart language and you can take online course to learn it. 

4. Flutter Basics

After you know about dart basics, flutter basics are also easy to understand and for this you have to understand this:

Open android studio and a project

Then, download the emulator

Then run the Android version and the project

You must understand how to structure the directory of the project and then you have to understand the files that are effective for the purpose. Now you have set the flutter and the basic platform is ready. 

5. Widgets

You can use the stateless widgets which will not change like image and button. Like the name, it does not have to change the state when there is any action that needs performance on the dice screen. 

State full widget is a widget which holds the widget current state. If there is no widget building method there is a state full widget with state build method that you can call single that we differently say set State. 

6. Flutter Layouts 

The layout model is also the widget in the flutter. Like rows, grid, columns fall under the layout widget. It helps others with visible widgets that one can arrange, align and contraints. 

7. Interactive widgets

There are widgets which will display different information on the screen and even arrange different types of widgets. If there is a real app, then making it interactive is essential and it is important to input different forms like taps, gestures to make it effective. Therefore, the widgets are established enough to balance the state.

8. Design app

It has form widget which will help you design the form that will efficiently manages with all types of essential requirements such as form, validation. To make the app interactive there need some inputs from the user and hence the use of the gestures is important. Well, in flutter this pre-built widget is always there to cover it up. The use of images makes it more engaging. You can make use of original images, royalty free images.

9. Show more list of data use

If you want to accommodate more data, then you can use the list on how to show the perfect app us. The list can be linear or horizontal. You can create grid list, horizontal list. The lists have more numbers than anything else. Also, there is no definite sense on how to build all the different items in a single form. 

10. Navigation through routes

The apps have many screens where you can display data in a systematic manner. In Flutter, you can use the Navigator to perform the operation. First, navigate to a brand-new screen and then back, then pass the data to your new screen and you will retrieve the new results. Now you can return from the data from your screen. To make the process efficient, Flutter named all the routes, then it passes the arguments in the named routes.

11. Networking is the next step to fetch data or even post data.
12. In flutter, the developer use JSon serialisation strategy for code generation. 
13. The dependency management helps you share the code all across the apps and you do not have to develop the thing from the scratch. 
14. State management is an art that you must understand for its good.
15. The final step comes with testing in all forms before the final launch of the app in the market.
