Does Flutter work like a browser? How is it different from a WebView based application?

To answer this question simply: Code you write for a WebView or an app that runs similarly has to go through multiple layers to finally get executed. In essence, Flutter leapfrogs that by compiling down to native ARM code to execute on both platforms. “Hybrid” apps are slow, sluggish and look different from the platform they run on. Flutter apps run much, much faster than their hybrid counterparts. Also, it’s much easier to access native components and sensors using plugins rather than using WebViews which can’t take full use of their platform.
