How to Dynamically Add Markers in Google Maps with Flutter

Are you looking to enhance your Flutter application by integrating Google Maps with dynamically displayed markers? If you're capable of showing a map with specific latitude and longitude but are unsure how to implement dynamic markers for shops, you're not alone. In this guide, we'll walk you through the entire process of setting up markers in Google Maps with Flutter using data from an API.

Problem Statement

You have successfully displayed a map using Flutter, but now you want to show markers representing various shops based on dynamic latitude and longitude values fetched from an API. Let's break down how to implement this efficiently.

Solution Overview

To add dynamic markers in Google Maps, you need to follow these steps:

Initialize Variables: Set up the necessary variables for your Google Map.

Create the Map Widget: Develop a user interface widget to display the map.

Make API Calls: Retrieve location data from your backend API.

Generate Markers: Convert the received data into markers and add them to the map.

Let’s dive deeper into each part.

Step 1: Initialize Variables

First, you should declare the required variables that will help manage the Google Map and store marker information.

Step 4: Generate Markers

After fetching the data and creating marker instances, those markers are stored in the markers variable, which is then utilized in the MapViewData widget. Make sure to call your Mapdata() function at the appropriate life-cycle method, such as initState().
