# How to Set Up a Restaurant Reservation System with FlutterFlow

- Tool: FlutterFlow
- Difficulty: Beginner
- Time required: 25-35 min
- Compatibility: FlutterFlow Free+

## TL;DR

Build a restaurant reservation system that matches party size to available tables. The Firestore data model includes restaurants, tables with seat counts and locations, and reservations with date, time slot, and status. Users select a date and party size, then see available time slots filtered by tables that fit their group. Booking creates a reservation document linked to a specific table, and a confirmation screen shows the details. An admin view displays all reservations for a given day organized by table in a grid layout.

## Building a Table Reservation System in FlutterFlow

This tutorial builds a restaurant reservation system where table assignment depends on party size, not just time availability. Unlike a simple appointment scheduler, this system considers table capacity, indoor versus outdoor seating preferences, and special requests. It includes both the customer booking flow and an admin day-view for restaurant staff to manage the floor. This pattern works for restaurants, event venues, co-working spaces, and any business with capacity-based scheduling.

## Before you start

- A FlutterFlow project with Firestore configured
- Basic understanding of Backend Queries and DateTimePicker in FlutterFlow
- Firestore collections for restaurants, tables, and reservations
- Familiarity with Page State variables

## Step-by-step guide

### 1. Create the Firestore data model for restaurants, tables, and reservations

Create a restaurants collection with fields: name (String), address (String), capacity (int), operatingHours (Map with startHour and endHour as ints, e.g., 11 and 22). Create a tables collection with fields: restaurantId (String), tableNumber (int), seats (int), location (String: indoor, outdoor, bar). Create a reservations collection with fields: tableId (String), restaurantId (String), userId (String), date (String, formatted YYYY-MM-DD), timeSlot (String, e.g., '18:00'), partySize (int), status (String: confirmed, cancelled, completed), specialRequests (String), createdAt (Timestamp). Add 6-8 sample tables with varied seat counts.

**Expected result:** Firestore has restaurants, tables, and reservations collections with the table-based reservation model.

### 2. Build the booking form with date and party size selection

Create a ReservationPage with Route Parameter restaurantId. Display the restaurant name and address at the top from a Backend Query. Add a DateTimePicker configured for date-only selection with a minimum date of today. Add a party size DropDown with options 1 through 10. Store both selections in Page State: selectedDate (String) and selectedPartySize (int). Add a Find Available Times button that triggers the availability query in the next step. Disable the button until both date and party size are selected.

**Expected result:** Users can select a date and party size before searching for available time slots.

### 3. Query available time slots filtered by table capacity

On Find Available Times tap, query the tables collection where restaurantId matches and seats >= selectedPartySize. For each qualifying table, query reservations where tableId matches, date equals selectedDate, and status equals confirmed. Generate time slots in 30-minute increments between the restaurant's startHour and endHour. Remove slots that overlap with existing reservations. Display available slots as tappable Containers in a Wrap widget, each showing the time and table location. Grey out unavailable times. Store the selected slot and table in Page State.

**Expected result:** Available time slots display based on real table capacity and existing reservations.

### 4. Create the reservation and show confirmation

Add a special requests TextField below the time slots for dietary needs or celebration notes. Add a Confirm Reservation button. On tap, create a document in the reservations collection with tableId, restaurantId, userId, date, timeSlot, partySize, status set to confirmed, specialRequests, and createdAt timestamp. Navigate to a ConfirmationPage that displays: restaurant name, date, time, party size, table number, and location. Include an Add to Calendar button using a Launch URL action with a Google Calendar event link, and a Cancel Reservation button that updates the status to cancelled.

**Expected result:** A reservation is created in Firestore and the user sees a confirmation with all booking details.

### 5. Build the admin day view for managing reservations

Create an AdminDayViewPage accessible to restaurant staff. Add a DateTimePicker at the top for selecting the day. Query all reservations for the selected date and restaurantId. Display a grid layout: rows represent tables (sorted by tableNumber), columns represent time slots. Each cell shows either empty (available) or the reservation details (guest name, party size, status with color coding: green for confirmed, red for cancelled, blue for completed). Staff can tap a reservation to view details or update its status.

**Expected result:** Restaurant staff see a table-by-time grid of all reservations for any given day.

FIRESTORE DATA MODEL:
  restaurants/{restaurantId}
    name: String
    address: String
    capacity: int
    operatingHours: { startHour: 11, endHour: 22 }

  tables/{tableId}
    restaurantId: String
    tableNumber: int
    seats: int

  reservations/{reservationId}
    tableId: String

  Page State: selectedDate, selectedPartySize, selectedTimeSlot, selectedTableId

  WIDGET TREE:
    SingleChildScrollView
      Column
        ├── Text (restaurant name + address)
        ├── DateTimePicker (date only, min: today)
        ├── DropDown (party size: 1-10)
        ├── Button ("Find Available Times")
        │     On Tap: query tables where seats >= partySize
        │             → for each table, check reservations on date
        │             → generate available 30-min slots
        ├── Wrap (available time slot Containers)
        │     └── Container per slot
        │           Text (time + location)
        │           On Tap: set selectedTimeSlot + selectedTableId
        ├── TextField (special requests, multiline)
        └── Button ("Confirm Reservation")
              On Tap: create reservation doc → navigate to Confirmation

```

## Common mistakes

- **Not considering party size in the availability query** — A table for 2 shows as available for a party of 6, leading to frustrated guests who arrive and cannot be seated together. Fix: Always filter tables by seats >= selectedPartySize before checking time slot availability.
- **Generating time slots outside restaurant operating hours** — Showing a midnight slot for a restaurant that closes at 10 PM wastes screen space and confuses users. Fix: Read the restaurant operatingHours document and only generate slots between startHour and endHour.
- **Not handling concurrent bookings for the same table and time** — Two users can book the same table at the same time if both check availability simultaneously and both see it as open. Fix: Use a Firestore transaction or Cloud Function to atomically check availability and create the reservation. Reject if a conflict exists.

## Best practices

- Filter tables by party size so guests are always seated at appropriately sized tables
- Generate time slots dynamically from restaurant operating hours, not hardcoded values
- Use Firestore transactions to prevent double-booking the same table and time slot
- Show table location (indoor, outdoor, bar) alongside time slots so guests can choose
- Include a special requests field for dietary needs, celebrations, or accessibility requirements
- Color-code reservation status in the admin view for quick visual scanning
- Allow cancellation up to a configurable cutoff time before the reservation

## Frequently asked questions

### How do I handle walk-in guests in the reservation system?

Add a Walk-In button on the admin page that creates a reservation with status set to walk-in and the current time as the slot. This occupies the table in the system without requiring a customer account.

### Can I set different operating hours for different days?

Yes. Change the operatingHours field to a Map of day names to start and end hours. When generating slots, look up the hours for the selected day of the week.

### How do I limit how far in advance guests can book?

Set the DateTimePicker maximum date to a date calculated as today plus your booking window, such as 30 days. This prevents reservations too far in the future.

### Can guests choose a specific table?

Yes. After filtering by party size and time, display available tables as cards showing table number, seats, and location. Let the user tap their preferred table instead of auto-assigning one.

### How do I send reservation confirmation emails?

Create a Cloud Function triggered by new reservation documents. The function reads the reservation and user details, composes a confirmation email with date, time, and table info, and sends it via a service like SendGrid or Firebase Extensions.

### Can RapidDev help build a restaurant management platform?

Yes. RapidDev can build complete restaurant systems with reservation management, waitlist queuing, table layout visualization, POS integration, and automated reminder notifications.
