升級到最新的 Flutter 穩定版本后 CachedNetworkImage 拋出錯誤

Question

我今天將 Flutter 升級到v1.12.13版本，但是當我運行該應用程序時，出現以下錯誤 -

Compiler message:

我正在使用最新版本的CachedNetworkImageProvider 。

Answer 1

這目前看起來像是一個活躍的問題。 將版本更改為2.0.0-rc暫時修復錯誤。

Answer 2

如官方頁面所述

Flutter 1.10 中 ImageProvider.load 的重大變化

Flutter 團隊在 Flutter 1.10.15（目前僅限 Master 頻道）中對 ImageProvider 進行了重大更改。

如果您遇到以下錯誤之一，請升級到 2.0.0-rc。

切換到緩存網絡圖像：^2.0.0-rc

如果問題仍然存在，請嘗試flutter clean並運行。
