我想用flutter_launcher_icons软件包更改应用程序图标，但在我执行flutter run后，我得到了以下错误，即使我从未编辑错误中提到的文件
这是错误：

PS C:\Flutter\appname> flutter run
Launching lib\main.dart on Pixel 5 in debug mode...
C:\Users\jjkla\.gradle\caches\transforms-3\8de94d7eb39fc01aa715c73f850e88dc\transformed\core-1.6.0\res\values\values.xml:5:4: Invalid <color> for given resource value.

表示颜色无效的文件部分：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr format="reference" name="nestedScrollViewStyle"/>
    <color name="androidx_core_ripple_material_light">#1f000000</color>

    <color name="notification_icon_bg_color">#ff9e9e9e</color>
    <dimen name="compat_button_inset_horizontal_material">4dp</dimen>

我重新安装了Android Studio，做了Flutter清理，更新了Java，运行Flutter医生都没有成功。以前有没有人遇到过这个错误？
