【flutter】错误：No MaterialLocalizations found.

场景是替换了一下闪屏图之后就报了这个错误，清除包啥的都不行，先记录一下

No MaterialLocalizations found.

AppBar widgets require MaterialLocalizations to be provided by a Localizations widget ancestor.
The material library uses Localizations to generate messages, labels, and abbreviations.

To introduce a MaterialLocalizations, either use a MaterialApp at the root of your application to include them automatically, or add a Localization widget with a MaterialLocalizations delegate.

The specific widget that could not find a MaterialLocalizations ancestor was: AppBar
