Mastering Location Features in No-Code Apps: From Autocomplete to Geo-Filters

If you're using no-code platforms like FlutterFlow, Adalo, or Glide, you've likely tried to build a location-based feature: maybe a search page where users select their city and browse nearby events, businesses, or communities. But making that experience feel smooth , a working map, an autocomplete text field, meaningful filters , isn't as no-code-simple as it first looks.

This guide will help you implement 3 key location features in your app: manual search with predictive autocomplete, automatic location via device, and effective geographic filtering.

1. Manual Location Input with Autocomplete

Users should be able to start typing a city or address and see intelligent suggestions. For this, you'll want to integrate an API that supports predictive search, like Google Places Autocomplete.

In most no-code tools, you'll:

• Add a TextField for manual input.
• Use the Google Places Autocomplete plugin or connect to the API with a custom action.
• Bind the dropdown suggestions to the API's response.
• When a user selects a suggestion, capture both the place name and corresponding lat/lng.

Tip: Store both the place display name and the coordinates in your local state. This allows you to use the same value whether the user selected a place manually or via device location.

2. Automatic Location via Device GPS

If the user allows location access, grab their latitude and longitude coordinates using a GPS plugin or your app's native location capabilities. Once you have those coordinates:

• Reverse-geocode them using the Google Maps API or a free alternative like Nominatim.
• Store the result (e.g. city name) in your state.
• Write both lat/lng and name to your search fields so it's interchangeable with manual input.

Pro move: Let users toggle between “Use My Location” and “Search by City”. Both paths write to the same state variables so your queries always work the same way.

3. Filtering By Area (and Optionally, Category)

Once you've captured the user’s location:

• Use a geo-radius query to show only data points within X kilometers/miles of that location.
• Most cloud databases like Firestore, Supabase, and Xano now support geospatial filters.
• Add a dropdown or list to let users optionally choose a category (e.g. Restaurants, Gyms).

Your query logic can look like this:

• If category is selected: Filter by location AND category.
• If no category: Filter only by location.

In many no-code tools, this means duplicating your query or using conditional logic blocks. Tools like FlutterFlow even let you show/hide certain lists based on whether a filter is active.

Bonus idea: If your results list feels clunky, use a MapView that shows markers based on the filtered query. Clicking a marker can open a detail popup or navigation page.

Common Pitfalls (And How to Avoid Them)

• Autocomplete not working: Double check your API key permissions , Google often disables Places Autocomplete by default.
• Location not updating the input field: Make sure your state variables are being updated correctly after each action (manual or GPS).
• No results showing: Check your query filters. Use test data and hardcode lat/lng first to test the radius.
• Category filters not applying: Ensure you're not always tying the query to a non-null category. Use conditional logic.

Summary

Powerful location-based features are absolutely possible with no-code platforms , but only if you structure your data, state, and API calls smartly.

Stick to these principles:

• Use shared state variables for all location sources
• Normalize your filters for user-friendly logic
• Leverage dynamic queries that adjust to user input

Your users will thank you for a smooth, intuitive experience , and you’ll be able to take all the credit without writing traditional code.

Happy building 🚀
