Combine registration, Android and iOS to make a small plugin.
Summary - Platform plugin
A complete plugin brings three pieces together: registration on the Dart side via registerWith, a bridge via MethodChannel, and replies via onMethodCall on Android and handle on iOS. All sides use the same channel name.
// Dart
MyPlugin.registerWith();
// Android
"my_plugin" channel -> onMethodCall
// iOS
"my_plugin" channel -> handlePractice Print the three sides
In main, with three separate print calls, print 'Dart', 'Android', 'iOS' in order.
Starter code
void main() {
// 'Dart', 'Android', 'iOS' üç ayrı print ile yazdır
}Sample solution
void main() {
print('Dart');
print('Android');
print('iOS');
}Expected output
Dart Android iOS
