Overview

Flutter Maps is a powerful data visualization widget that displays statistical information for a geographical area. Its rich feature set includes tile rendering from OpenStreetMap, Azure Maps, Bing Maps, Google Maps, and other tile providers with marker support and shape layers with features like selection, legends, labels, markers, tooltips, bubbles, color mapping, and much more.


Shape layer

Render GeoJSON data as custom maps or any shape on a shape layer for powerful data visualization in Flutter Maps. Customize the maps to the desired look using built-in options. For example, you can render a map of the world or any particular country.

Maps shape layer support.


Tile layer

An interactive tile layer allows you to load and customize map tiles from web map tile services such as OpenStreetMaps, Azure Maps API, Bing Maps API, Google Maps Tile API, TomTom, Mapbox, Esri’s ArcGIS, etc. Use markers to denote the specific latitude and longitude in the tile layer as required. Zoom and pan the tile layer to navigate across the regions and take a closer look.

Maps Tile Layer Support


Data labels

Data labels in the shape layer provide basic information about shapes by displaying their names. If required, trim or hide the labels when they exceed the shape bounds.

Maps data label support.


Selection

Highlight a shape to focus on the selected area. Use functionalities like page transitions, showing detailed information about a selected area, and more during this interaction.

Maps Selection Support


Legend

Legends in the shape layer provide clear information on data plotted in the Flutter Maps widget through shape and bubble colors.

Maps Shape Legend

Shape legend

Show a legend for data represented by shapes. You can also use the legend-toggling feature to let the end user see only the required shapes and data much easier.

Maps Bubble Legend

Bubble legend

Maps Gradient Bar Legend

Gradient style

Use gradient colors as the bar background to show changes in regional data.


Color mapping

Categorize the shapes on a map by customizing their color based on their underlying data. Flutter Maps supports two types of color mapping: equal color mapping and range color mapping.

Maps Equal Color Mapping.

Equal color mapping

Apply a specific color to a shape solely based on its data. For example, apply colors to countries based on their organization membership.

Maps Range Color Mapping

Range color mapping

Apply colors to shapes if their data falls within a specific range. For example, apply colors to countries based on their population density.


Map bubbles

Add information to shapes, such as population density and number of users. Bubbles can be rendered in different colors and sizes based on the settings of their assigned shape.

Maps Default Bubble

Color customization

Customize the color of a bubble and its transparency based on data.

Maps custom bubble.

Size customization

Customize the size of a bubble based on data to enhance its readability.


Interactive map markers

Denote important locations using multiple markers in Flutter Maps. Use built-in marker icons such as circles, diamonds, rectangles, and triangles. Also, use any type of widget as a custom marker, from text widgets for showing simple labels to any type of complex widget. Marker animations can be used to highlight a single location or a group of locations. Update the marker position dynamically to the desired location in scenarios like real-time location updates. Use a marker’s tap or click interaction for custom functionalities like navigation, showing a custom info window, showing different options based on application scenario, etc.
