Is there a converter method for the object in firestore in flutter?

I am trying to find a way to convert my customized object in order to send it to firestore. I tried to look at the Firestore documents but found nothing referencing to flutter. Is there a way to convert the object and send it to firestore?

As Doug Stevenson says in his answer here, you can store raw data in firestore documents. For specifically flutter, you have to create a Blob from your object. See this for what a blob is. To convert to the Uint8List that the Blob constructor takes, see this answer converting Dart objects into a JSON string and converting this string into a byte array. It doesn't seem like a great method, but I personally don't know any alternatives. The basic gist of the answer is to serialize the object to a JSON string.

Alternatively, if possible, you can create a conversion method that stores your object as a Map and write that to your document. This reference shows a javascript example, but shows a similar concept.
