Answer 1

you can use this plugin device_policy_manager it helps to lock the device immediately as if the lock screen timeout has expired at the point of this call. just follow the installation steps in the readme and this how u can use it

/// Return `true` if the given administrator component is currently active (enabled) in the system.
final status = await DevicePolicyManager.isPermissionGranted();

/// request administrator permission
await DevicePolicyManager.requestPermession("Your app is requesting the Adminstration permission");

/// lock the phone
await DevicePolicyManager.lockNow();
