🚀 Introducing Flutter Web Emulator

Are you tired of launching heavy Android emulators or setting up physical devices just to get a quick preview of your Flutter app? 😓 Say goodbye to sluggish performance and resource-hungry tools!

We’re excited to introduce the Flutter Web Emulator, a powerful and lightweight VS Code extension built specifically for Flutter developers. It brings a realistic mobile experience directly to your development environment – no Android Studio, no emulator installs, and no stress on your CPU.

✨ What is Flutter Web Emulator?

Flutter Web Emulator is a Visual Studio Code extension that provides a phone-like interface for running and testing Flutter web applications. Whether you're a student, beginner, or pro dev, it offers a seamless, intuitive preview environment — all without leaving your editor.

⚡ Key Features

📱 Realistic Phone Interface

Simulates a true mobile experience with UI components like navigation buttons, status bar, and more — so you can test as if you’re on a real device.

🔥 Hot Reload Support

Supports Flutter’s experimental web hot reload, enabling real-time previews and fast iteration cycles.

📐 Professional Device Presets

Choose from multiple device configurations like iPhone 14, Pixel 7, or iPad, ensuring your app looks perfect across screen sizes.

🔄 Device Rotation

Easily switch between portrait and landscape to test responsiveness.

🎮 Interactive Controls

Test in-app navigation using Home, Back, and Recent Apps buttons.

✋ Touch Simulation

Simulates ripple effects and touch gestures for an authentic UX experience.
