Espresso is a test framework used to write Android UI tests, and part of the Android SDK. The Espresso API encourages test authors to think in terms of what a user might do while interacting with the application - locating UI elements and interacting with them. At the same time, the framework prevents direct access to activities and views of the application because holding on to these objects and operating on them off the UI thread is a major source of test flakiness.

Flutter is an open-source mobile application development framework created by Google. It is used to develop applications for Android and iOS, as well as being the primary method of creating applications for Google Fuchsia.
Flutter is well known for native app development, if you have android studio installed on your system, you can quickly start using it. This might not be the best choice for you if you do not wish to learn a new language, i.e. Dart and you do not know it already.
As Espresso works on the ideal thread if the threads are not handled properly by the developing team it can lead to challenges in the execution of your tests.
Depends more on the developer's code
we cannot develop tests as individual frameworks, we share the repository with developers.
We need to be cautious while making changes in the tests, as we share same repository
Occasionally updates to the Flutter SDK result in wide-sweeping changes that seem to not be thoroughly tested and considered. Flutter sometimes evolves too fast for its own good.
While the 3rd-party Flutter package ecosystem is vast and rich, 1st-party support for basic things (audio/video playback, battery information, Bluetooth services, etc.) are lacking. You are occasionally forced to rely on an open-source package for use-cases that other platforms have native support for.
Documentation, particularly around testing, is lacking. While there are some great docs, like the Dart Style Guide, many Flutter-focused support documents are lacking in quality and real-world usability.
Flutter allows you to architect an app however you want. While this is a great feature, it also adds complexity and leads to the current state of Flutter's state management, where there are 50+ options on how to organize your app, with very little official guidance or recommendations from the Flutter team. For a beginner, this can create decision paralysis.
As our app is complete on Android Espresso is the best choice over Appium Fewer efforts in Espresso over Appium, as Espresso provides some built-in library to perform the operation. Easy to use, Espresso is very easy to understand and we can perform operations with very little code. Developers can contribute, as they have good command over Java and Kotin languages and also use Espresso for unit testing.
I have experience with react and React Native. I would say that the idea behind all those frameworks are quite similar. However, I found the javascript-based frameworks a bit more accessible as you could utilise your javascript knowledge. Here, Flutter works with its own language. This has advantages and disadvantages sometimes. I found the community around javascript frameworks bigger and therefore sometimes more helpful. However, Flutter does a good job here as well. I think the main argument for Flutter is its usability for less experienced developers. If you do not have knowledge in javascript or other programming languages then I think it is much easier to start with Flutter than with another framework like react. I think the package that you get form scratch is better than in the other frameworks were you have to set up and learn a lot more before you can start.
The rapid development capabilities of Flutter allow us to build apps we could not have previously considered commercially viable, opening new revenue streams.
Free and open licensing made adoption very easy (ie. free/low cost!).
In comparison to Qt, our time spent arguing with build tools and perfecting development environments has decreased substantially.
