How can My app prevent a user from installing and launching certain apps?

Question

I am developing an app to be installed on children's phones, and once it is installed I would like it to prevent them from being able to install certain apps, let's say from a black list (not completely disabling the play store app).

It would also be great if it blocked launching pre-installed apps from the "black-list".

I am trying to avoid creating a "kiosk mode" app.

Is this possible?

Your application need to have admin privileges to control such conditions.

Scroll through this link for more detailed explanation.

Go through this link for Device administration feature This is irrespective of Cross Platform apps or Native Apps.

In Flutter, even if you try creating a plugin which can communicate to native layer, still the restrictions remain the same.

Moreover this ability gives you much more access than usual applications. Which is considered as dangerous.

Few API's are deprecated considering the security aspects. Details are given below.

With the release of Android 9.0, the following policies are marked as deprecated when invoked by a device admin, but the APIs otherwise continue to function.

USES_POLICY_DISABLE_CAMERA
USES_POLICY_DISABLE_KEYGUARD_FEATURES
USES_POLICY_EXPIRE_PASSWORD
USES_POLICY_LIMIT_PASSWORD
