Creating a Flutter Data Table with Dynamic Content

When developing apps with Flutter, displaying data in a structured and user-friendly manner is crucial. One common issue developers face is utilizing dynamic lists to populate data tables. In this guide, we'll explore how to transition from a simple ListView to a fully functional DataTable using your dynamic content.

The Problem

You may have already implemented a ListView to display employee data efficiently. However, switching to a DataTable can seem daunting, especially when you want to ensure that all data points are accurately represented. The key challenge here is how to properly index your data and use that information to populate the columns of the DataTable.
