ios/Classes/BatteryLevelPlugin.m - The iOS-platform specific implementation of the plugin API in Objective-C.

android/src/main/java/com/rudderstack/batteryLevel/BatteryLevelPlugin.java - The Android platform-specific implementation of the plugin API in Java.

lib/batteryLevel.dart - The Dart API for the plugin.

This command creates a plugin project in the batteryLevel folder with the specialized content given as follows:.

rudderstack - template = plugin - platforms = android, ios - a java - i objc batteryLevel

Below is the example command to create a plugin package for Android, iOS platforms while using java for Android and Objective-C for iOS.įlutter create - org com.Use the -a option to specify the language for Android or the -i option to specify the language for iOS.This value is used in various package and bundle identifiers in the generated plugin code. Use the -org option to specify your organization, using reverse domain name notation.Available platforms are Android, iOS, web, Linux, macOS, and Windows. Use the -platforms= option followed by a comma-separated list to specify the plugin supports platforms.Use the -template=plugin flag with the Flutter create command.It uses the Android BatteryManager API and the iOS device.batteryLevel API, via a single platform message, getBatteryLevel().

The following example demonstrates how to call a platform-specific API to retrieve and display the current battery level. It then calls into any number of platform-specific APIs-using the native programming language-and sends a response back to the client, the app's Flutter portion, as shown below:Īrchitectural Overview of how Platform Channels Work Between Different Platforms Building a Custom Plugin Using Flutter Getting Started

The host listens on the platform channel and receives the message.

The Flutter portion of the app sends messages to its host - the iOS or Android portion of the app, over a platform channel.

To create a custom plugin, let us understand the Flutter architecture in detail: Working of the Flutter SDK Across Different Channelsįlutter's built-in platform-specific API support does not rely on code generation but rather on a flexible message-passing style using a Platform Channel.

The custom plugin follows a basic mechanism based on Flutter's flexible system that allows calling platform-specific APIs available in Kotlin or Java on Android or Swift or Objective-C code on iOS. So, we wanted to develop a solution that allowed us to leverage our existing Android and iOS SDK to create the Flutter SDK which is meant to run on either your Android or iOS devices.Īfter much brainstorming, we decided to develop a custom plugin in Flutter. We developed the Android and iOS SDKs to include features such as storing event details and persisting user details on the database. In this post, we will learn how to develop a custom plugin using Flutter.Īt RudderStack, we wanted to develop a Flutter SDK to compliment our existing set of SDKs-which included Android and iOS at the time (now we have more than 5!). One interesting thing about Flutter is that it works with existing code and is used by developers and organizations worldwide. It is used to build high-quality native interfaces on Android and iOS using a single codebase. Flutter is Google's free and open-source UI application development toolkit.
