Flutter: How to detect that the app is running on LD Player-CodePudding

I am working in a Flutter app with some security requirements, one of them is to prevent the app from working in Emulators, just real devices, in order to prevent the screenshots and screen recordings from the Emulators.

I have used safe_device and device_info_plus packages to detect whether the app is running on Emulator or Physical device and every thing is working fine but when I tried LD Player Emulator the packages failed to detect that it is emulator because it is very good at mocking the real device.

So any ideas to detect that the device is running on LD Player?

Here is the output from device_info_plus which might be helpful:

I think I could use the two following values from the output of device_info_plus package to decide that the app is working on an Emulator because they seems very generic but I am not sure and TBH afraid to because I do not want to block any user by mistake:

"host": "ubuntu",
"device": "aosp",

CodePudding user response：

Check this Package https://pub.dev/packages/safe_device

bool isRealDevice = await SafeDevice.isRealDevice;

this method returns false if running device is an emulator
