Possible to develop ride-sharing app? like Grab

Hi, Thunkable X, i done my community research about this project, since it is possible in the classic tho with some basic features, i already check the possible blocks and components that might be use using thunkable X, but it wont satisfied the project since

  1. it dont have custom google marker
  2. Only one firebase
If you will recommended using Google Map Api with the support of webviewer, do you have any recommended source code of it, since all backend will be much done in a code based and implement in a block.. Anyone thoughts? I would love to discuss about this project, since this project already exist in our city but in android version and i want to start the IOS.

If you can work the API, it’s easy enough to send data to it.

the thunkable github has documentation on this

start here
Directions API  |  Google Developers

then here

then here

for example. i use this to make a bubblemap, i create the JSON data in my app. i transmit the data to the following HTML document stored on my github server space.

wow!Thank you so much for this information, one more thing, if it dont consume too much time, can it be a favor to show how to implement this in a block way inside of a project? so anyone or me can view this as a open source code, this i believe some might get into this kind of project soon.

can ell progress/
