clearInlineSlot method
Clears the inline slot at slotKey, if any. No-op if nothing is active
there. reason is how the removal is reported; the default is the user's,
and null reports nothing.
Implementation
void clearInlineSlot(String slotKey,
{DismissReason? reason = DismissReason.userClose}) {
final removedConfig = _slotConfigs.remove(slotKey);
final removedPayload = _slotPayloads.remove(slotKey);
if (removedConfig == null && removedPayload == null) return;
if (removedPayload != null) {
_notifyInlineRemoved([removedPayload], reason);
}
notifyListeners();
}
