There are a large number of high-quality and well-accepted frameworks and technologies. Some of them are as follows:

• Xamarin
• React Native
• Ionic
• Cordova

So, you might think it's hard for a new framework to find its place on an already full field, but it's not. Flutter has benefits that make space for itself, not necessarily by overcoming the other frameworks, but by already being at least on the same level as native frameworks:

• High performance
• Full control of the user interface
• Dart language
• Being backed by Google
• Open source framework
• Developer resources and tooling

Let's look at each of these in more detail.
