在进行 --release 构建时如何解决构建失败问题？

Question

在我的 flutter 应用程序中，我无法进行构建。构建失败。

我已经执行了以下命令来在我的 Android 手机中进行构建：

flutter build apk --release

通过执行上述命令，我收到以下错误：

Font asset "BoxIcons.ttf" was tree-shaken, reducing it from 320764 to 888 bytes (99.7% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when bu ilding your app. Font asset "Iconsax.ttf" was tree-shaken, reducing it from 992800 to 2992 bytes (99.7% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when bu ilding your app.
Font asset "MaterialIcons-Regular.otf" was tree-shaken, reducing it from 1645184 to 3440 bytes (99.8% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-ico ns flag when building your app.

我正在使用 flutter 版本：

Flutter 3.24.3 

帮我解决这个问题。

Answer 1

发生这种情况是因为您正在使用的

read_pdf_text

包中的 compileSdkVersion 已过时。

解决此问题的最快决定是在您的

subprojects

中添加另一个

build.gradle

块（根块，而不是

app/build.gradle

）并向上

compileSdkVersion

到处：

subprojects {
    afterEvaluate {
        // Version must be 31 or newer, 34 here is just example because it is used by Flutter itself.
        compileSdkVersion 34
    }
}

最好的决定是切换到更现代的软件包，其依赖项是最新的。
