Place Tracker

A sample place tracking app that uses the google_maps_flutter plugin. Keep track of your favorite places, places you've visited, and places you want to go. View details about these places, show them on a map, and get directions to them.

Goals

• Learn how to create an interface composed of GoogleMap and other widgets.
• Learn how to show, control, and modify a GoogleMap widget.
• Learn how to place a marker on a map.

The important bits

place_map.dart

This page shows a full-screen GoogleMap widget with place markers. Provides examples of how to stack other widgets on top of a GoogleMap widget, how to add markers to a map, and how to make other flutter widgets interact with the GoogleMap widget.

place_details.dart

This page shows a detailed view of a single place. Provides examples of how to place a GoogleMap widget inside of a ListView and how to disable certain touch gestures on the map.
