 回答：无障碍模式下目前Flutter Engine有bug，已经提交issue和PR给flutter啦。请参考这个issue：https://github.com/alibaba/flutter_boost/issues/488及其分析。提交给flutter的PR见这里：https://github.com/flutter/engine/pull/14155
 
 ### 5. 在ios模拟器下运行最新的flutter boost会闪退
-回答：因为模拟器下flutter默认会将voice over模式打开，所以其实就是辅助模式，这回触发上面的bug：“在ios中voice over打开，demo在点击交互会crash”。
