  What is a Plugin? A plugin can be defined as a piece of software that allows you to add capabilities to your app.  But first, you should check  pub.dev  to see if the plugin you are going to create already exists or not. For authoring plugins, there is a mechanism in Fluter that allows you to interact with platform-specific code and also allows you to publish your plugins on pub.dev so that others can use them. Create the plugin template To get started  Flutter  works with templates for plugins that make it easy. You can specify which language you want to use when you create the plugin template. The default is Kotlin for Android and Swift for iOS. Add the platform-specific code Now you have two separate implementations for the same functionality, one for iOS and one for Android.

  So, How does native platform support be done by using Platform channels? We will read about it in this blog. Basically,  Flutter  has its own supple system that allows users to call platform-specific APIs which might be in Java code on Android, or in Kotlin or in Swift or Objective-C code on iOS. Dart code has no direct access to the platform-specific APIs of the Android SDK and iOS Cocoa Touch. What are Platform Channels? Platform channels are a simple mechanism that provides communication between the Dart code and the platform-specific code of a host app. This means you can show a platform service in your host app code and have it invoked from the Dart end. Or vice versa. It will be possible with plugins to create a Dart API backed by an iOS implementation which is written in Objective-C or Swift and an Android implementation which is written in Java or Kotlin and then it will be packaged up as a Flutter or Android or iOS triple stick together using platform channels....

  The mobile app industry is enormous, and every day new apps are entering this space.  88%  of the user's mobile time is spent within the mobile apps. There are at least 2.87Mn apps available on Google Play Store alone. The total number of apps on the Apple store stands at  1.96Mn . These are huge numbers, and they are going to keep increasing. With such exciting stats backing mobile app development, enterprises must think of app-first if it helps engage better. Having said this, the biggest dilemma that presents itself before companies is whether to go Android/iOS first with their solution. For startups and small/medium businesses, you should essentially try identifying ways in which you can enter both OS simultaneously. With cross-platform app development, you can release apps for all the users and gain more traction. We just solved one problem, giving rise to another- what framework to use for cross-platform apps. We will talk about why flutter app development is...
