The Hybrid/Cross-Platform app development platforms like Flutter are a favorite of the developer community. The usability of the code on different platforms saves time, reduces errors, lowers costs, and all updates can also be rolled at once.
The open-source app development framework Flutter (uses languages including C++ and Dart) is an initiative of Google. The built-in widgets provide for easy building of user interface on Flutter. Because it has its own engine for drawing the widgets, it does not rely on the OEM widgets or WebView.
Hot reloading also provides for faster development. No compiling of the app is required for you to preview the changes in the codes. Among other benefits like building up robust UI, Flutter also provides for experimentation and fast fixing of bugs.
