Let's shake the Flutter tree
The more platforms a Flutter application supports, the more code a project can have that is needed only for one platform and not needed for others. How to make sure that unnecessary code does not get into the final platform-specific build? And how to check that it really did not get?
In Flutter, there is a Tree-shaking mechanism, which is designed exactly for these purposes. Many Flutter developers have heard about it, but not everyone really understands what it is and how it actually works. Let's try to figure it out.
Flutter. Many faces of Platform Integrations
If you can't achieve something in Flutter, you can do it at the platform level and then use it in the cross-platform part, you only need to remember Java or Kotlin for Android and Swift or Objective-C for iOS, And don't forget about Flutter for the Web with JavaScript or TypeScript. It turns out that there are a whole bunch of integration options with the native part, and in this talk, I'm going to analyze all of them with examples.

Flutter. New Approach to Web Development.
In the modern world, it is very rare for businesses to only require a website or only a mobile application. Typically, it is necessary to create both a website and a mobile application together. In such a situation, there is always a choice of which technologies to use. There are generally three options: developing separate web and native mobile applications, with the mobile development team handling the native app; building a web application for mobile devices, such as a PWA (Progressive Web App); or using a cross-platform solution that allows reusing the code between platforms.
Recently, an interesting alternative to traditional approaches emerged—a new framework by Google called Flutter. With Flutter, you can develop mobile, desktop, and web applications. However, the approach used in Flutter for Web differs significantly from traditional web application development. So, can we consider Flutter applications for the web as web applications?
