FakeScreenSecurity class

A host-VM fake ScreenSecurity — counts the backup screen's protection requests so a widget test can assert it engages on show and releases on dispose. isScreenshotBlockSupported is configurable so a test can drive both the Android (block) and the elsewhere (advise-a-private-setting) copy.

Properties

disableCount ↔ int

getter/setter pair

enableCount ↔ int

getter/setter pair

engages → bool

What enable reports back — whether the (fake) native side ENGAGED. Defaults to the capability, mirroring a correctly wired host; pass engages: false to play a capable platform whose host never wired the native handler (the B1 shape — the UI must stay pessimistic).

late, final

hashCode → int

The hash code for this object.

no setter, inherited

isScreenshotBlockSupported → bool

Whether THIS platform can actually block screenshots (Android only). The CAPABILITY signal used for adapter selection and by the test fakes — the UI copy no longer reads it (engagement truth is enable's return).

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

disable() → Future<void>

Release the protection when the sensitive screen leaves the tree.

override

enable() → Future<bool>

Request that the OS prevent screenshots / hide the screen from the app switcher while the sensitive screen is visible. Best-effort and idempotent; a failure never breaks the screen (the protection is defence-in-depth, not the gate).

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
