How to Convert a List of Maps into a Single Map in Flutter

When working with data structures in Flutter, you may often find yourself needing to convert a list of maps into a single map. This task involves transforming a collection of key-value pairs represented in individual maps into one consolidated map. In this guide, we will walk you through a solution to this common issue and provide clear steps to achieve your desired outcome.

The Problem

Imagine you have a list of maps, where each map contains two keys: key and value. Your goal is to create a single map where each key becomes the key for the new map, and the corresponding value becomes its value. Here’s an example of what the initial data might look like:

The Solution

To convert the list of maps into a single map, you can follow these straightforward steps. We'll use a simple Dart function to demonstrate how this can be accomplished.

Step 1: Initialize Your List of Maps

First, ensure that your list of maps is properly defined. Take care to use double quotes around keys and values to adhere to Dart's syntax rules.
