Question

我有一个Flutter应用，该应用在Android和iOS上一直崩溃。
我没有任何堆栈跟踪。该应用程序仅在iOS和Android上最小化。
我只在一段时间后才收到崩溃报告。
我不明白问题是什么。
我认为是由于某些内存问题。

下面是我的Android build.gradle文件。我正在使用ListView，在ListView内加载图像。

        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 {

我认为问题是您正在使用大尺寸的图像加载到嵌套列表视图中，而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。导致由于应用程序占用过多内存而导致内存不足的异常。请从firebase或sql等数据库中加载该内存，或加载分辨率较低的png小图片。希望有帮助。

应用因发布模式中的内存问题而崩溃
