Flutter Map – Location plugin

A flutter_map plugin to request and display the users location and heading on the map. The core features of the plugin are:

• Customization: The location button and marker can be completly customized.
• Energy efficiency: The location service is turned off if the app runs in the background.
• Usability: Developers are empowered to ensure a good user experience.

User experience

Status

• The location button can be changed dependening on the location services status. For example also Google Maps shows a different icon if the location service is off.
• The marker icon can be changed depending on the location accuracy.
• It's possible to show the information (e.g. in form of a snackbar) to the user that the user location is outside of the map bounds.
• The location heading is also shown for devices without an gyroscope. We patched flutter_compass for that.
