I’m using a web project compiled with Flutter. Whether it’s a web app or a hosted app, the operations run smoothly when it’s executed on the emulator, but it becomes very laggy when running on a real device.
webOS TV apps are web-based. It’s not much different from general web app development. However, webOS TV uses different web engines depending on the webOS version. So please check compatibility with the web engine first. And app performance optimization is up to you. Please consider that TVs have lower specifications than PCs, and try reducing TV resource usage. We recommend less than 250MB. Resource Monitor enables you to monitor the resource usage of the webOS system in real time. Thank you.
If your app runs smoothly on the emulator but lags on a real device, it could be due to hardware limitations, background processes, or unoptimized code. For performance-critical apps, always test on multiple real devices to ensure optimal user experience.
