释放模式下由于内存问题导致应用程序崩溃

Question

我有一个在 Android 和 iOS 上不断崩溃的 Flutter 应用。
我没有得到任何堆栈跟踪。该应用程序只是在 iOS 和 Android 上最小化。
我只是在一段时间后才收到崩溃报告。
我不明白问题是什么。
我认为这是因为一些内存问题。

以下是我的 Android build.gradle 文件。我正在使用 ListView 在 ListView 中加载图像。

        def localProperties = new Properties()
        def localPropertiesFile = rootProject.file('local.properties')
        if (localPropertiesFile.exists()) {
            localPropertiesFile.withReader('UTF-8') { reader ->
                localProperties.load(reader)
            }
        }
        def flutterRoot = localProperties.getProperty('flutter.sdk')
        if (flutterRoot == null) {                      
            throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
        }
        configurations.all {

我认为问题在于您使用大尺寸的图像加载到嵌套列表视图中，我看不到任何数据库，这意味着您正在从应用程序本身静态加载它们。这会导致内存不足异常，因为该应用程序占用了太多内存。请从诸如 firebase 或 sql 之类的数据库中加载它，或者加载具有低分辨率的小 png 大小的图像。希望对您有所帮助。
