Ensure your Flutter app is configured for web deployment.
Enable Web Support:
Run the following command to enable web support in your Flutter project:
flutter config --enable-web
Build for Web:
Build your Flutter app for the web:
flutter build web
Step 2: Push Your Code to GitHub
Step 3: Deploy to Vercel
Now that your code is on GitHub, you can deploy it to Vercel.
Log in to Vercel:
Go to vercel.com and log in with your GitHub account.
Create a New Project:
Click on the "New Project" button.
Select the GitHub repository where your Flutter app is hosted.
Configure the Build Settings:
Vercel will automatically detect your Flutter project.
Set the following build settings:
Build Command:
flutter/bin/flutter build web --release
Output Directory:
build/web

Deploy:
Click the "Deploy" button.
Vercel will start building your Flutter web app. This process may take a few minutes.
Step 4: Access Your Deployed Site
Once the build is complete, Vercel will provide you with a live URL for your deployed Flutter web app. You can access your app by clicking the link provided in the Vercel dashboard.
Step 5: Custom Domain (Optional)
If you want to use a custom domain for your Flutter web app:
Go to the "Domains" section in your Vercel dashboard.
Add your custom domain and follow the instructions to configure DNS settings.
Troubleshooting
If you encounter issues during deployment, check the following:
Flutter Web Compatibility:
Ensure your app and its dependencies are compatible with the web platform. Avoid using libraries like dart:ffi that are not supported on the web.
Build Logs:
Check the build logs in the Vercel dashboard for detailed error messages.
Flutter Version:
Ensure you're using a stable version of Flutter. Run flutter upgrade to update your Flutter SDK.
