How to Design Dynamic Android and iOS Apps Using Flutter: Part 4

Flutter Code Base II

Okay, so dear readers, in the third installment of the Flutter series, we have captured the widgets of Flutter and studied different types of widgets. So, now let’s start our journey ahead and look at the other Flutter code bases.

Gestures

In Flutter, gestures can be available in the form of tap, double tap, long press, vertical and horizontal drags, etc. To provide all these gesture controls, Flutter provides developers with the cool GestureDetector widgets. The example of gesture widget is:

new GestureDetector(

onTap: () {

  setState(() { _birthday = true});

},

child: new Container(

 child: new Text(‘Happy Birthday!’),

),

)

Flutter has numerous lucrative features of its own also. It has a set of interesting animations and has introduced internalization on the platform also. Moreover, the features of Flutter are related to the web applications, Android apps, and iOS graphics, so for the new Flutter user, it’s very easy to adopt this new app development environment. That’s why developers, you should immediately head over to flutter.io and develop your very first Flutter app. So, let’s study the Flutter app development on the basis of different platforms.

Flutter For Web Developers

The web users can develop their Flutter app on the basis of HTML code. The Flutter HTML code for app development is:

.text{

    font: 200 14px Arial;

}

An example of Dart code is given below:

 

Text(

   “Happy Birthday”,

   style: new TextStyle(

   fontSize: 14.0

   fontWeight: FontWeight.w200,

   fontFamily: “Arial”

 ),

)

Another example of HTML code is:

 

.contain{

    background-color: #26c6da;

}

Another example of Dart code is:

 

Container(

    color: Colors.cyan[400]

)

Flutter For Android developers

For Android developers, Flutter is a very easy and simple platform to build mobile app development. The components of the Flutter are quite similar to the Android equivalent. That’s why it is quite easy for the Android developers to understand the visual effects of the Flutter as they will find numerous similarities with the Android UIs. Such as;

  1.    The Android View has few rough similarities with the widgets in Flutter. Well, a view is the basic foundation of everything that’s happening in the Android, similarly, in Flutter, everything revolves around the widgets. However, widgets are not truly views, as they are mere descriptions of the user interface that will be converted to the actual View Object. So, it’s similar to Flutter widgets, but not really.
  2.    In Flutter, you will get a material library which uses widgets that implement the material design. The guidelines mentioned in the material library are also used in the Android platform, so here developers don’t have to face any problem.
  3.    In Android, developers use Canvas and Drawable to draw and paint. In Flutter, you have the similar Canvas API to do the painting. So, for Android developers, this one is the yet another similarity between the Flutter and Android.
  4.    In Android, developers Intents to navigate between Activities and in Flutter uses Navigator and Routes to navigate between screens. This is a very useful similarity between the Android and Flutter.

Well, that was the interesting features of the Flutter for the Android developers and for the web developers. To know more features and uses of the Flutter for the iOS developers and React developers, stay connected and keep reading. To know more benefits of the Flutter please read the next article. Otherwise, head over to the official website of the Flutter to find out other similarities and differences.
