使用 Tree Shake 图标构建 Flutter Web

Question

当我使用命令

--tree-shake-icons

将 flutter 构建到 Web 平台时，我收到此错误。

This application cannot tree shake icons fonts. It has non-constant instances of IconData at the following locations:

file:///Users/xxx/Documents/flutter/packages/flutter/lib/src/widgets/icon_data.dart:22:9

file:///Users/xxx/Documents/hxgy/flutter/projectName/lib/utils/font_util/font_utils.dart:13:7
Target web_-release_bundle failed: Exception: Avoid non-constant invocations of IconData or try to build again with
--no-tree-shake-icons.

我需要flutter自动压缩字体图标的大小，因为图标太大，所以我没有使用

--no-tree-shake-icons

指挥官。

Answer 1

Flutter Web 尚不支持

--tree-shake-icons

。 这可能有帮助。

Answer 2

现已支持此功能。
