When I first started with Flutter, I was hyped. That excitement lasted right up until I installed Android Studio and realized I had just turned my humble laptop into a jet engine. Everything lagged. My RAM was crying. Booting a sample app felt like launching Photoshop… three times.
If you’ve got a low-end PC or just don’t want to waste half your RAM on tools you don’t need, I’ve got some good news: you can build Flutter apps without Android Studio or an emulator, and the experience is way smoother than you’d expect.
In this post, I’ll show you a lean, beginner-friendly setup that’s fast, easy, and runs great on modest machines. You’ll go from installing Flutter to running your first app on a real Android device, no bloat, no sweat.
Why Skip Android Studio and Emulators?
- Resource hog: Android Studio is heavy, especially on lower-end systems.
- Slow startup: Emulators are notoriously slow, and even fast machines struggle.
- Overkill: Most beginners don’t need all the advanced features IDEs offer.
- Better testing: Physical devices give real-world feedback, touch, screen sizes, and performance.
So instead of the typical heavyweight stack, I put together a setup that focuses only on the essentials:
🛠️ Tools You’ll Use
Here’s the minimalist toolkit:
- VS Code: Lightweight editor with just the Flutter & Dart extensions.
- Flutter SDK: The main framework, of course.
- Physical Android Device + USB – Real hardware > virtual device.
- Scrcpy: A slick screen mirroring tool for real-time device display on your PC.
And if you want to skip a few manual steps, I also built a small free tool that automates part of the setup and makes launching your project a one-click process (link at the end of the post 😉).
🔧 Step-by-Step Setup
1. Install Flutter SDK
Start by downloading Flutter from the official Flutter site. Extract the archive somewhere like C:\flutter or your home directory on Linux/macOS.
Then add the flutter/bin directory to your system’s PATH variable so you can run flutter from any terminal.
Finally, verify everything’s okay with:
flutter doctor
This checks for missing dependencies and gives setup suggestions.
2. Install VS Code and Extensions
Download Visual Studio Code. Once installed, add these extensions:
- Flutter (from Dart Code)
- Dart (from Dart Code)
These give you hot reload, widget trees, snippets, and more, without the heavy IDE baggage.
3. Enable Developer Mode on Your Android Device
You’ll be using a real phone instead of an emulator, it's lighter, faster, and more realistic.
Here’s what to do:
- Go to Settings > About Phone
- Tap Build number 7 times to enable Developer Options
- Head to Developer Options and enable USB Debugging
- Plug in your phone and allow USB permissions when prompted
Then run:
flutter devices
You should see your phone listed. If not, you may need drivers (on Windows) or to install ADB tools (on Linux/macOS).
4. Install and Run Scrcpy
This is the magic sauce. Scrcpy mirrors your Android screen to your desktop in real time, without the lag or resource drain of an emulator.
You can install it via:
- GitHub Releases
- Or package managers like Scoop or Chocolatey (Windows)
Once installed, run scrcpy in your terminal, and your device screen pops up on your desktop, touch works, mouse works, and latency is super low.
5. Launch Your App
Now you're ready to run your app:
- Open your project in VS Code
- Connect your phone
- Run:
flutter run
Or hit F5 in VS Code.
The app runs directly on your device, and mirrors via Scrcpy. Hot reload works like magic, and your PC stays cool and quiet.
🧠 Why This Works (and Works Well)
- VS Code is snappy and customizable.
- Flutter CLI handles all the build/run logic.
- Real devices give better debugging signals and real-world testing.
- Scrcpy feels like an emulator without being one, it's lightweight, fast, and surprisingly powerful.
This setup is perfect for:
- Students or devs with 4–8GB RAM machines
- Those just learning Flutter
- Anyone tired of emulator lag or Android Studio boot times
📦 Bonus: Free Setup Tool
To make life easier, I created a small free tool that helps automate part of this setup. It:
- Launches your project with
flutter run - Opens Scrcpy automatically
- Simplifies environment setup
👉 The tool is available for free at the bottom of the detailed setup guide on Kumotechs:

It includes a .bat file for Windows and a quick Markdown setup guide to help you get started faster.
Final Thoughts
I’ve used this setup on a low-spec laptop (imagine: 4GB RAM, Celeron, cracked screen) and still managed to run, build, and debug real Flutter apps with no drama. If you’re new to Flutter or just want a cleaner way to work, this setup is game-changing.
Flutter doesn’t have to be heavy. You just need the right tools, and maybe a little rebellion against Android Studio.
