  Flutter is a mobile app development framework created by Google that allows developers to build high-performance, cross-platform applications using a single codebase. It has gained a lot of popularity since its launch in 2017 and has become a favorite among developers due to its features like hot reload, widget-based UI, and easy-to-learn programming language. However, like every other technology, Flutter also has its limitations, which developers need to consider before using it. In this blog, we will discuss some of the limitations of the Flutter framework. Large app size One of the significant limitations of the Flutter framework is that it can result in large app sizes. Flutter apps have a minimum size of 4MB, which is much more significant than the traditional native apps built using Java or Kotlin for Android and Swift or Objective-C for iOS. This size can further increase if developers use third-party plugins or libraries, resulting in slower download and installation ti...

  Flutter has been growing in popularity among mobile app developers due to its impressive features and capabilities.
