如何获取此 UI 元素的高度和宽度（以像素为单位）？

我收到此错误

错误：AndroidManifest.xml:18:9-45 中的属性 application@label value=(flutter_bloc_pattern) 也存在于 [:DynamsoftBarcodeReader] AndroidManifest.xml:13:9-41 value=(@string/app_name)。

构建失败并出现错误

        Suggestion: add 'tools:replace="android:label"' to <application> element at AndroidManifest.xml:16:5-39:19 to override.
