ios - Flutter Firebase 回调不会在 iOS 13 上触发，但在 Android 上可以正常工作

Question

当我遇到以下情况时，我目前正在开发一个 flutter 应用程序:

在 Android 上，一切都按预期工作。如果应用程序在前台，onMessage被称为，onLaunch如果应用程序在后台，依此类推。

在 iOS (13) 上，不会调用任何回调。通知到达，显示正确的图标、文本和标题，当我单击应用程序打开的通知时，但没有触发任何回调。如果应用程序已经在前台，则不显示通知(如预期的那样)，但 onMessage也不叫。

这是我发送的有效载荷:

{
  "data": {
    "click_action": "FLUTTER_NOTIFICATION_CLICK",
    "key1": "value1"
  },
  "to": "RECEIVER",
  "notification": {
    "sound": "default",
    "title": "Title",
    "body": "Message"
  }
}

flutter 代码:

firebaseMessaging.configure(
  onMessage: (Map<String, dynamic> message) {
    log.info('Firebase::onMessage: $message');

    _handleMessage(message);
  },
  onResume: (Map<String, dynamic> message) {
    log.info('Firebase::onResume: $message');

    _handleMessage(message);
  },
  onLaunch: (Map<String, dynamic> message) {
    log.info('Firebase::onLaunch: $message');

    _handleMessage(message);
  },
);

AppDelegate.swift:

我尝试在有和没有以下行的情况下运行该应用程序

if #available(iOS 10.0, *) {
    UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}

我在 XCode 的功能选项卡中启用了推送通知、后台获取和远程通知。

我正在运行 Flutter 1.12.13(beta channel )，但是我也尝试使用 flutter stable 运行应用程序，这导致了相同的行为。

Answer 1

编辑:
对于 ios 13，Readme.md 上的指南是错误的。
检查 2 件事。

删除代码

if (@available(iOS 10.0, *)) {
[UNUserNotificationCenter currentNotificationCenter].delegate = (id) self;
}

检查您是否有“flutter_local_notifications”库
然后，将其移除。

目前，我知道这是由 ios 13 更新引起的插件错误。
