I met the same question

[hanxu317317]

我正在处理这个问题.

[hanxu317317]

问题已经解决. 亲可以试一下.

[TreeLiked]

OK了哦

[ismanong]

没有迁移androidX就迁移啊，这是什么问题，现在很多插件都是androidx，与时俱进呗，

[hanxu317317]

@ismanong 我会尽快的. 年底事情太多要做了

[ismanong]

@hanxu317317 我不是说你 不好意思 我表达不好，我意思提这种问题不太好，因为我用的时候没问题，如果打包提示更新androidX，开发者应该第一时间了解androidX并尝试去更新，而且更新androidx并不是什么坏事，但如果提问题到这里，还得麻烦作者去兼容什么的，这个兼容可要可不要。反而冗余，哈哈。
另外还是感谢作者，再贫瘠的pub库里做了这么一个稳定的省市区选择器插件。目前没出过问题，已经用了大半年了

希望作者早点解决一下吧 我只能flutter SDK 版本回退才能使用这个插件

[k-dylan]

我是在添加 image_picker插件后出现的这个问题，照着这个处理，暂时没有那个问题了： flutter/flutter#27254 (comment)

The same version with you. I try to update my project to be Androidx, and problem was solved!
modify file android/gradle.properties

android.enableR8=true
android.useAndroidX=true
android.enableJetifier=true
