countries_world_map 0.0.1

A simple CustomPainter that draws a customizable world map on the screen.

Countries_world_map

This flutter package creates a world map with the CustomPainter and over 450 different paths creating all the borders. The widget "WorldMapPainter" has as few inputFields.

• defaultCountryColor This takes in a Color that will be the default color for all countries

• countryColors This takes in a CountryColors class. In this class you can assign a custom Color to each country using the country codes. For example:

  • uS = United States
  • nL = Netherlands etc.

  There are 250 different countries / islands to color.

• backgroundColor This is the color of the Canvas. By default, this will be transparent.

Memory usage

The map is big, so (re)building the widget can be expensive. That's why the WorldMap uses a RepaintBoundry to prevent it from unnecessary repaints. If you change a Country Color and call SetState() the widget will repaint.

! Warning

On the iPad Pro 2018 there has been found some memory issues when re-painting the World Map many times in a short time period. If you have memory issues, you might want to limit the possible repaints.

WorldMapPainter

If the WorldMap widget does not give the results you would like to see, you can also use the WorldMapPainter in your own defined CustomPainter. This will give you all the paths with the option to custom color each country.
