Description

https://github.com/alibaba/flutter_boost/blob/6df80cc1ea425cde1bac7d0265407977221061df/ios/Classes/FlutterBoostPlugin.m#L206

After [listeners removeObject:listener];, if listeners is empty, it should be removed from self.listenersTable.

It is recommended to append the following method after [listeners removeObject:listener];:

`if (listeners.count == 0) [self.listenersTable removeObjectForKey:key];`

Research direction

Open ios/Classes/FlutterBoostPlugin.m around line 206 and trace the listener-removal path in FlutterBoostPlugin. Confirm that an empty listeners collection is no longer retained in self.listenersTable after removal. Done when the empty entry is removed while the existing behavior remains intact.
