2.2.6版本依赖冲突

Resolving dependencies...
Because no versions of device_info_plus match >12.2.0 <13.0.0 and device_info_plus 12.2.0 depends on ffi ^2.1.4, device_info_plus ^12.2.0 requires ffi ^2.1.4.
And because agora_rtm >=2.2.6 depends on ffi ^1.2.1, device_info_plus ^12.2.0 is incompatible with agora_rtm >=2.2.6.
So, because flutter_tabicall depends on both agora_rtm ^2.2.6 and device_info_plus ^12.2.0, version solving failed.

升级RTM到2.2.6之后遇到了版本依赖冲突问题，为什么RTM2.2.5都是用的ffi的最新版，反而2.2.6用了ffi的老版本
