如何在Firestore Flutter中获取昨天日期的所有记录？

import 'package:cloud_firestore/cloud_firestore.dart';

DateTime now = DateTime.now();
DateTime yesterday = now.subtract(Duration(days: 1));

Firestore.instance
    .collection('your_collection') // 替换为你的集合名称
    .where('date_field', isGreaterThanOrEqualTo: yesterday)
    .where('date_field', isLessThan: now)
    .get()
    .then((QuerySnapshot snapshot) {
  snapshot.documents.forEach((DocumentSnapshot doc) {
    // 处理每个记录
    print(doc.data);
  });
})
.catchError((error) {
  // 处理错误
  print(error);
});
