我更新了Gradle之后出现了这个错误(我还在更新Gradle的同时添加了maven {jitpack.io}和geofirestore依赖项):

我怎么解决这个问题？

这里我的Project build gradle:

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'


        // NOTE: …

现在一周，有时当我 HotReload 我的更改没有应用（日志说它是 HotReload 但实际上他们不是）和我 HotRestart 时一样，所以我被迫停止并重新运行应用程序（和有时删除构建）！

    Doctor summary (to see all details, run flutter doctor -v):
[?] Flutter (Channel beta, v1.15.17, on Microsoft Windows [version 10.0.17763.1098], locale fr-FR)

[?] Chrome - develop for the web

我在 Android Emulator 9 Pie 上运行我的应用程序。

编辑：我试图使 AndroidStudio 的缓存无效并重新启动，并且还尝试了另一个模拟器，但它没有解决问题......

我有一个这样的功能：

exports.deleteUser = functions.https.onCall(async(data, context) => {
    let id = context.auth.uid;
    console.log('Delete user: ' + id);

    //delete from algolia
    usersIndex.deleteObject(id);
    console.log(id + 'Deleted from algolia');

    //delete user following
    await admin.firestore().collection('users').doc(id).collection('Following').get()
      .then(async(snapshot) => {
        for await (const document of snapshot.docs) {
          await admin.firestore().collection('users').doc(document.documentId)
            .update({
              'NumberOfFollowers': FieldValue.increment(-1)
            });
          await admin.firestore().collection('users').doc(document.documentId).collection('Followers')
            .doc(id).delete();
        }
        return console.log('Following of ' + id + ' deleted');
      });
...

但是当我尝试将它部署到 firebase 函数时，我收到以下错误：

!  functions[deleteUser(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Code in file index.js …

当我尝试构建我的应用程序时，我在控制台中收到此错误：

我在 Xcode 11.3.1

我有最新版本的 Flutter。

我尝试构建另一个我几个月前已经构建的旧应用程序，它运行良好。

编辑：我试图将构建更改为旧版，但我遇到了同样的错误，它仍然说“注意：使用新的构建系统”，而在我的日志中它说“检测到旧版构建系统”...

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

我执行此代码是为了从 firestore 获取图像并将其用作地图标记的图标。

final StorageReference storageReference =
FirebaseStorage().ref().child("ProfilePictures/" + widget.userId);
String avatarDownloadPath = await storageReference.getDownloadURL();
final File _avatar = await DefaultCacheManager().getSingleFile(avatarDownloadPath);
Uint8List __avatar = await _avatar.readAsBytes();
BitmapDescriptor avatar = BitmapDescriptor.fromBytes(__avatar);

setState(() {
  _markers.add(Marker(markerId: MarkerId("UserPosition"), position: userLocation, icon: avatar ));
});

此代码有效，但我想将图像设置为圆形，但我不知道该怎么做...

如果你也知道如何在周围添加一个圆圈并像这样设置动画，我会非常满意：

（我没有找到更具有代表性的东西，但我只想要一个圆圈）
