This tutorial uses the Google Map js file instead Ionic 2 native google map plugin. Why because the native google map plugin of Ionic 2 is not working. Actually, the native plugin is not generating the Google Map. That’s why I choose the Google Map js file.
Do you know why is not working the native way?
If you use the code mentioned in the Ionic documentation, it will throw some error like the function not found in the google map instance. I thought it may be documented incorrectly. This is the problem with the map native plugin.
