【Flutter】The binary version of its metadata is 1.8.0, expected version is 1.6.0.

问题描述

Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

---

原因分析：

The binary version of its metadata is 1.8.0, expected version is 1.6.0.
jetified-kotlin-stdlib-1.8.22.jar这两个就是关键信息；需要将kotlin的版本升级到1.8.22或以上都可以。

解决方案：

build.gradle (android)里修改kotlin的版本为1.8.22，然后Sync Now。

ext.kotlin_version = '1.8.22'
