I'm getting this exact same error, but using Flutter 1.22.5. It worked fine a week or two ago when I last built for iOS.

这个是版本信息，不不是flutter2，也报这个 Flutter 1.26.0-2.0.pre.401 • channel unknown • unknown source Framework • revision da5a454d5c (8 weeks ago) • 2021-01-17 01:24:03 -0500 Engine • revision 609036f2bf Tools • Dart 2.12.0 (build 2.12.0-236.0.dev)

已解决fatal error: could not build module 'r_scan'

找到r_scan的pubspec.yaml文件 1、注释掉flutter: ">=1.12.0 <2.0.0" 2、platforms修改为 androidPackage: com.rhyme.r_scan pluginClass: RScanPlugin 3、clean工程，再次编译即可 4、再不会就随便找一个可以用的其它plugin，对比修改一下即可

[navyzhou926]

再补充几条： 1、r_scan/ios/r_scan.podspec文件ZXingObjC引用修改为：s.dependency 'ZXingObjC' 2、源码中所有的头文件引用修改为：

import <ZBarSDK/ZBarSDK.h>

import <ZXingObjC/ZXingObjC.h>

3、去用吧，good luck

[navyzhou926]

android我直接引用没有什么问题，ios需要按照上述修改后，用本地插件的方式引用到工程中，明显作者对于ios引用此插件的兼容性没有做过多的测试，大部分使用者，ios估计是直接报错，大家要给作者加油打气，维护好此插件

[anchao-lu]

已经换了其他插件，作者 null safety 好像都不打算维护了

[navyzhou926]

已经换了其他插件，作者 null safety 好像都不打算维护了

你用的哪个插件，我测试的目前较多star的插件，要么只支持android，要么扫描效果不是很好。这个插件虽然作者可能不维护了，我底层修改一些代码后，还是比较稳定的
