Are you in dilemma on deciding which framework to utilize for cross-platform mobile app development between React Native & Flutter? Read this article to comprehend the developer's viewpoint on the same.

1. React Native vs Flutter — Which is Best?
Are you in trouble deciding which framework to utilize for cross-platform
mobile app development between Flutter and React Native? Continue reading
this article to know more.
Cross-platform application development is gaining huge popularity nowadays.
The greatest advantage to use upon is its ability to create apps on multiple
platforms. A couple of cross-platforms are utilized today because of the ease
offered to the developers. React Native, for instance, introduced by social
media giant Facebook got a decent response from developers. Additionally,
Google introduced Flutter with rival the prior one.
The leading market players and development frameworks — Flutter and React
Native have become top contenders competing to demonstrate their value
across cross-platform mobile app development. Individuals looking to build up
applications more quickly in less expense are scratching their head as they
discover it very difficult in distinguishing which framework best fits their
application idea.
The discussion here is focused on comparing the two cross-platforms React
Native & Flutter based on their features and what value they are imparting to
the developers.
What is Flutter & React Native? A Sneak Pee
 Flutter is introduced by Google provides the ability to create native
applications on Android and iOS both simultaneously.

2.  React Native is Facebook’s JavaScript framework utilized for writing real,
native apps for iOS and Android.
Comparing React Native and Flutter:
 Based on Programming Language Performance
React Native uses JavaScript as a programming language that is broadly
utilized by developers which makes it easy to adopt. When it comes to
developing hybrid applications, they may confront issues concerning libraries,
architecture and native components. If we look at the brighter side of it, React
Native allows for the highly secure and seamless development of applications
in most cases.
If we talk about Flutter in terms of performance, it gives an edge over React
Native for creating hybrid applications. Flutter utilizes Dart programming
language that is seldom utilized and less popular in the developer community
through which we can without much of a stretch conclude React takes the
lead.
 User Interface (UI)
Flutter apps look great on both iOS and Android due to their one codebase
and component- rich nature that implies the application will act naturally and
copy their native components whereas, React Native app components looks
simply like the native ones. Thus if you want your application to look almost
the same across platforms then you can utilize React.
 Based on Tooling & Documentation
Flutter offers smooth documentation and that ultimately improves the job of
developers. On the other hand, React Native has disorganized documentation
and it lags far behind Flutter in this case.
If we compare both this framework based on tools offered, Flutter includes a
wide range of IDEs and tools. It has support for Android Studio and Visual
Studio Code also. React Native doesn’t fall behind and it also has to offer table
a wide scope of libraries and tools for both Android & iOS app development.
 Based on Stability
Flutter was in its alpha stage, which isn’t appropriate for long-term project
development. However, Google recently updated it with Flutter Beta 2 that
proffers improved tools and systems for stable development.

3. React Native, without a doubt, is a stable cross-platform for quite a while and
it additionally has a wide community of developers and contributors.
 Testing Support
The React Native community has no official support for UI level testing and
integration; it utilizes third-party tools like Detox and Appium, whereas flutter
has a rich set of testing features like widget testing which makes it a lot more
prominent than React.
Considering the comparison above, you can almost certainly figure which
framework will suit best for your mobile app development.
