Added #

• Added the alias method to LDClient. This can be used to associate two user objects for analytics purposes with an alias event.
• Added the autoAliasingOptOut configuration option. This can be used to control the new automatic aliasing behavior of the identify method; by setting autoAliasingOptOut to true. identify will not automatically generate alias events.
• The SDK now supports the ability to control the proportion of traffic allocation to an experiment. This works in conjunction with a new platform feature now available to early access customers.

• The SDK implementation is now null-safe.
• The minimum Flutter version has been raised to 2.0.0.
• The minimum Dart version has been raised to 2.12.0.
• The minimum supported Android API version has changed from 16 to 21.
• The underlying SDK on Android has been updated to 3.1.1 from 2.13.0. See the Android SDK changelog for details on improvements.
• The underlying SDK on iOS has been updated from 5.2.0 to 5.4.3. See the iOS SDK changelog for details on improvements.
• The identify method will now automatically generate an alias event when switching from an anonymous to a known user. This event associates the two users for analytics purposes as they most likely represent a single person.
