Method channels example

Flutter MethodChannel Example

This repository contains examples of how to use MethodChannel in Flutter to communicate between the Flutter part and native code (Android in this case).

Description

Step 1: Get Platform Version

• Create a MethodChannel named "platform_version".
• Invoke the native method to obtain the platform version.
• Display the result in an AlertDialog.

Step 2: Data Channel ("dataChannel")

• Create a MethodChannel named "data_channel".
• Define a method in native code to receive a string from Flutter and return it concatenated with "- Native".
• From Flutter, send the string "Hello Flutter" to native code through the channel.
• Display the response on the user interface.

Step 3: Bidirectional Channel ("bidirectionalChannel")

• Implement a bidirectional MethodChannel named "bidirectional_channel".
• Define two methods in native code: flutterToNative and nativeToFlutter.
• From Flutter, invoke the flutterToNative method and send a string.
• From native code, invoke the nativeToFlutter method and send a different string.
• Display both strings on the user interface.

Running Tests

To run unit tests that verify the MethodChannel functionality, follow these steps:

1. Open a terminal in the project's root directory.
2. Execute the following command:

flutter test
