## 6. 日历提醒未使用自定义提示音
|
||
|
|
|
||
|
|
**文件**: `apps/lib/core/notification/services/reminder_scheduler_service.dart`
|
||
|
|
|
||
|
|
**问题描述**:
|
||
|
|
已添加 `apps/assets/reminder_sound/1.WAV` 自定义提示音文件，但代码中未使用，仍使用系统默认铃声：
|
||
|
|
|
||
|
|
```dart
|
||
|
|
// 当前代码
|
||
|
|
const androidDetails = AndroidNotificationDetails(
|
||
|
|
_channelId,
|
||
|
|
_channelName,
|
||
|
|
// ...
|
||
|
|
playSound: true, // 使用系统默认
|
||
|
|
// 没有 customSound 配置
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
**根因**:
|
||
|
|
添加了资源文件但未在通知配置中引用。
|
||
|
|
|
||
|
|
**建议修复**:
|
||
|
|
1. 在 `pubspec.yaml` 添加 assets 路径：
|
||
|
|
```yaml
|
||
|
|
flutter:
|
||
|
|
assets:
|
||
|
|
- assets/reminder_sound/
|
||
|
|
```
|
||
|
|
|
||
|
|
2. 在通知配置中引用自定义铃声：
|
||
|
|
```dart
|
||
|
|
// Android
|
||
|
|
final androidDetails = AndroidNotificationDetails(
|
||
|
|
_channelId,
|
||
|
|
_channelName,
|
||
|
|
playSound: true,
|
||
|
|
sound: RawResourceAndroidNotificationSound('reminder_sound/1'),
|
||
|
|
// ...
|
||
|
|
);
|
||
|
|
|
||
|
|
// iOS
|
||
|
|
const iosDetails = DarwinNotificationDetails(
|
||
|
|
presentSound: true,
|
||
|
|
sound: 'reminder_sound_1.wav',
|
||
|
|
// ...
|
||
|
|
);
|
||
|
|
```
|
||
|
|

## 7. 通知调度缺少变化检测（重复重建）
|
||
|
|
|
||
|
|
**文件**: `apps/lib/core/notification/services/reminder_scheduler_service.dart`
|
||
|
|
|
||
|
|
**问题描述**:
|
||
|
|
每次获取日历事件都会调用 `upsertEventReminders`，内部执行 `cancelEventReminders` + 重建，即使事件没变化：
|
||
|
|
|
||
|
|
```dart
|
||
|
|
Future<void> upsertEventReminders(event) async {
|
||
|
|
await cancelEventReminders(event.eventId); // 总是先取消
|
||
|
|
for (alarm in buildAlarmsForEvent(event)) {
|
||
|
|
await _scheduleAlarm(alarm); // 总是重建
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
**影响**:
|
||
|
|
- 通知 ID 变化导致系统重新调度，浪费资源
|
||
|
|
- 用户频繁访问日历时产生不必要的操作
|
||
|
|
|
||
|
|
**建议修复**:
|
||
|
|
```dart
|
||
|
|
Future<void> upsertEventReminders(event) async {
|
||
|
|
final existing = await _getScheduledAlarm(event.eventId);
|
||
|
|
if (existing != null && _isSameAlarm(existing, event)) {
|
||
|
|
return; // 跳过，没变化
|
||
|
|
}
|
||
|
|
await cancelEventReminders(event.eventId);
|
||
|
|
for (alarm in buildAlarmsForEvent(event)) {
|
||
|
|
await _scheduleAlarm(alarm);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
