ios - Flutter 崩溃 iOS - NSInvalidArgumentException

Question

有谁知道这个崩溃是什么？我在网上查了一下，有些结果似乎相似但不完全相同。以下是 Crashlytics 中的痕迹：

致命异常：NSInvalidArgumentException -[__NSCFString substringWithRange:]: Range {19, 9223372036854775788} 越界；字符串长度 0

这似乎与 EditText 有关（此崩溃发生在我的登录屏幕上），但我不知道是什么。只有 1 台设备受到影响 - 13.6.1 上的 XS Max。没有其他 XS Max 设备或 13.6.1 上的其他设备受到影响，仅此一个，可能是由于设备配置或其他原因？任何想法都会有所帮助。

附带说明一下，有没有办法从 Crashlytics 获取更多可读日志？就像可能得到 Flutter 会在 Debug 应用程序上抛出的确切错误？我没有使用 Swift 的经验，所以来自 iOS 的日志对我来说毫无意义。谢谢！
