I'm from following issue.
How to manage add and update data in Firebase
Initially I can make data in firestore following code.
However I would like to add car2 inside of cars after car1. I have no idea of it.
_firestore.collection('members').document(${loginUser.uid}).setData({ 'cars': { 'car1': { 'name': name, 'img_url': 'https://www.xxx.xxx/xxx.png', 'details': { 'type': carType, } } } Please give me advice.
