添加 flutter_launcher_Icons 后，gradle 構建失敗

Question

我添加了 flutter_launcher_Icons 包。 之后我的應用程序將無法在 android 上構建。 它失敗並出現錯誤。

這是--stacktrace

我該如何解決這個問題？

這是 pubspec 依賴項

Answer 1

我認為您在adaptive_icon_background屬性的十六進制代碼中缺少# 。

文檔說：

Adaptive_icon_background：用於填充自適應圖標背景的顏色（例如“#ffffff”）或圖像資源（例如“assets/images/christmas-background.png”）。

附帶說明一下，您可以使用 appicon.co 輕松生成應用程序圖標，如果需要，請按照此操作。
