Interactive Country Maps for Data Visualization

In this article, we'll introduce you to the interactive_country_map package, a powerful tool for creating interactive maps that allow users to select specific regions. This package is perfect for visualizing data and creating interactive experiences for your users.

Installation

To install the interactive_country_map package, add the following line to your pubspec.yaml file:

flutter pub add interactive_country_map

Demo

The interactive_country_map package offers a wide range of customization options to create tailored maps that meet your specific needs.

Interactive Map

To add an interactive map to your Flutter app, use the InteractiveMap widget. Specify the MapEntity enum value to select the desired map. For example:

InteractiveMap(mapEntity: MapEntity.world),

You can also customize the map's appearance using the InteractiveMapTheme class. For instance, to set a specific background color:

InteractiveMapTheme(backgroundColor: Colors.lightBlueAccent),

Color Mapping

The package provides flexible options for assigning colors to different regions. For example, to color all regions starting with "FR" in green, use:

mappingCode: { ...MappingHelper.sameColor(Colors.green.shade300, ["FR-A", "FR-B", ...]), },

Markers

Enhance your maps with markers by utilizing the Marker and GeoMarker widgets. Marker relies on Cartesian coordinates, while GeoMarker employs latitude and longitude for precise placement.

Group markers together using the MarkerGroup widget and customize their appearance, such as border and background colors:

MarkerGroup(
  borderColor: Colors.pink.shade600,
  backgroundColor: Colors.pink.shade300,
  markers: [
    Marker(x: 30, y: 40),
    GeoMarker(long: 2.294481, lat: 48.858370),
    // ...
  ]
),
