使用的包是extended_text: ^5.0.5，看这个报错，没太懂是我需要实现这个类，还是包本身缺少了这个类的实现。主要是编辑器环境也没报错

我看这个issue和我的报错是相似的，但是并不能提供有效的参考 #93

确保 Flutter 2.0，最新版本只是适配的，你如果是master branch的话，也许不支持

mojerro commented 3 years ago

了解了，我现在用的是beta channel，我试试stable

zmtzawqlp commented 3 years ago

只支持stable，没那么多时间维护，beta，dev，master是经常有api变动

mojerro commented 3 years ago

感谢大佬，stable是没问题的。主要是之前的beta channel一直用着没问题就没注意
