问题

在ios使用plugin调用dart侧方法报错,在Android可以正常调用

环境信息

提供Fair版本号

dependencies:
  fair: 2.7.0

相关截图【可选】

大概定位到问题了。fair_jsbase.js文件中有bigint类型在iOS14一下的系统上是不支持的，导致了加载js文件失败。我在iOS15系统上就可以跑通，iOS12的系统就会报错。 https://webkit.org/blog/11340/new-webkit-features-in-safari-14/ https://caniuse.com/bigint 这两个文章都有对bigint的支持有说明！ @zhiqingchen

这个可以先用其他类型替换BigInt吗，BigInt类型目前兼容性不好！ @yancechen
