我正在尝试在我的应用程序中的视图中设置地图,我遇到了这个问题:

CoreData:注释:无法在路径'/var/containers/Bundle/Application/35C61A40-48B9-40E0-A6F9-AB7492A15009/simply-convertor.app/GoogleMaps.bundle/GMSCacheStorage.momd/Storage.omo'CoreData上加载优化模型:注释:无法在路径'/var/containers/Bundle/Application/35C61A40-48B9-40E0-A6F9-AB7492A15009/simply-convertor.app/GoogleMaps.bundle/GMSCacheStorage.momd/Storage.omo'中加载优化模型'CoreData:注释:无法在路径'/var/containers/Bundle/Application/35C61A40-48B9-40E0-A6F9-AB7492A15009/simply-convertor.app/GoogleMaps.bundle/GMSCacheStorage.momd/Storage.omo'中加载优化模型

我向ViewContoroller添加一个空视图,并将其类型更改为GMSMapView.在viewDidLoad方法中,我从location创建一个新的map并初始化我的主mapView:

override func viewDidLoad() {
        super.viewDidLoad()
        placesClient = GMSPlacesClient.shared()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.startMonitoringSignificantLocationChanges()

        locationAuthStatus()
        print(location.coordinate.latitude, location.coordinate.longitude)
        let camera = GMSCameraPosition.camera(withLatitude: 31.9650070083707, longitude: 34.7899029677496, zoom: 6.0)
        let map = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
        self.mapView = map

        // Creates a marker in the center of the map.
        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2D(latitude: 31.9650070083707, longitude: 34.7899029677496)
        marker.title = "Home"
        marker.snippet = "Home"
        marker.map = mapView
    }

问题是什么？

我使用本指南https://medium.com/@level Fivecoder/ how-to-build-sign -and-distribute-your-flutter-android-application-using-azure-devops-and-appcenter-965382b85b8b 进行构建我的 azure devops 服务器上的脚本。

经过几次成功的构建后，我收到了下一个错误： ##[error]Error: The process '/Users/runner/hostedtoolcache/Flutter/1.20.1-stable/macos/flutter/bin/flutter' failed with exit code 1

有人遇到过这个错误吗？

更新

我按照建议将版本更改为 flutter 1.17.5，现在收到下一个日志错误：

我有一个通过电子邮件和密码使用 firebase 登录的应用程序。我正在使用 jetpack 与 MVVM 和干净的架构组合。

当从 firebase 登录完成时，我在视图模型中得到 true，然后在可组合项中监听此状态更改。

问题是我总是进入登录状态的 when 语句，它会导致无限循环，始终导航到下一个可组合项。

将视图中的特定行复制到此处：

when (val response = viewModel.signInState.value) {
        is Response.Loading -> LinearProgressIndicator(modifier = Modifier.fillMaxWidth())
        is Response.Success -> if (response.data) {
            navController?.navigate(Screen.HomeScreen.route)
        }
        is Response.Error -> LaunchedEffect(Unit) {
            scaffoldState.snackbarHostState.showSnackbar("Error signing out. ${response.message}", "", SnackbarDuration.Short)
        }
    }

我的看法：

@Composable
fun LoginScreen(
    navController: NavController?,
    viewModel: LoginViewModel = hiltViewModel()
) {
    val scaffoldState = rememberScaffoldState()
    Scaffold(scaffoldState = scaffoldState) {
        Column (
            modifier = Modifier
                .fillMaxHeight()
                .background(
                    Color.White
                ),
            verticalArrangement = Arrangement.Top, …
