• Apple Silicon Mac users should download the arm64 versions for optimal performance
• arm64 versions provide native Apple Silicon performance without translation layers

This repository contains a simple Flutter application that demonstrates basic functionality and cross-platform packaging.

1. Clone the repository:

   git clone https://github.com/suikan4github/demo-flutter.git
   cd demo-flutter

2. Install dependencies:

   flutter pub get

3. Run the application:

   flutter run -d linux

3. Run the application (on Windows):

   flutter run -d windows

3. Run the application (on macOS):

   flutter run -d macos

3. Run the application:

   flutter run -d web-server

Then, you will see output similar to the following:

 Launching lib/main.dart on Web Server in debug mode...
 Waiting for connection from debug service on Web Server...         11.9s
 lib/main.dart is being served at http://localhost:43075
 The web-server device requires the Dart Debug Chrome extension for debugging. Consider using the Chrome or Edge devices for an improved development workflow.

 Flutter run key commands.
 R Hot restart.
 h List all available interactive commands.
 d Detach (terminate "flutter run" but leave application running).
 c Clear the screen
 q Quit (terminate the application on the device).
