How to Design Dynamic Android and iOS Apps Using Flutter: Part 5


Flutter Code Base III

So, readers, first of all, thanks for showering us with your love and appreciation. And, welcome to the last part of the Flutter series. In the previous parts, we have covered basic characteristics of Flutter, it’s benefits and how it is useful for the Android and web developers. So, in this last part, we will wrap up the series by sharing the similarities of Flutter with the iOS and react native environment. So, let’s study the final part of Flutter series carefully people.

Flutter for iOS Developers

So, being an iOS developer, you can use your knowledge to develop the dynamic apps using the skills and tricks that you use in iOS development. Because similar to Android apps development in the iOS apps development, you will find numerous traits similar in Flutter also. So, if you are familiar with the iOS development framework, then you won’t have to face many difficulties in developing the app using the Flutter.

While developing iOS apps using the Flutter, you will see the following similarities between the two platforms:

  1.    The first similarity can be located in the iOS UI views and the Flutter widgets. Both seem quite equivalent to each other as UI view is the foundation of everything in the iOS platform whereas, in Flutter, widgets are the foundation of everything. However, widgets are not exactly like the UI views as they are the mere description of UI that get converted to the actual UI view objects.
  2.    In Flutter, the material library guidelines are used which are optimized for the iOS guidelines too. So, you will face no problem in understanding the Flutter material library if you are familiar with the iOS guidelines.
  3.    In the iOS platform, everything is wrapped in .opacity or .alpha files. But, in Flutter, you need to constrict the whole context in the widgets. The opacity widget is used to wrap the content in the Flutter.
  4.    In iOS to navigate, you have a UINavigationController tool to manage the view controllers.  Whereas, in Flutter, you have Navigator and Route to navigate between the screens. So, here Flutter is a bit different, but it’s not a very big difference.

Well, this is a brief screening between the iOS and Flutter platforms, to know more about the flutter for iOS developers read the documents provided on the official website of the Flutter.

Flutter for React Native Developers

So, if you are a big fan of react native environment and want to understand the Flutter from the point of view of a React Native developer. Then, we have briefly drafted the JS code requires in Flutter.

function demoCode() {



In the Flutter code, the start point is always the ‘main’ function:





Here is another example of the JS code:


var nullVar = null;

if (!nullVar ) {

//do something


In Flutter, the code is as follows:


var nullVar = null;

if (nullVar == null) {

//do something


This was just insight into the similarities and differences between the Flutter and react native. To know more about the topic visit the official website.


If you are thinking that we have covered everything about the Flutter in the five series, then you are wrong as Flutter has so much more to talk about. With the native performance, amazing responsiveness, flexible UI and faster development make it a perfect framework for mobile application development.

Flutter has a huge community which has been constantly developing and growing. So, we can say that Flutter is here to stay and make some changes. To start your Flutter journey, you can take the path of Google Codelab. So, best of luck people and develop your Flutter app now.
