Flutter Firestore 中的商店列表

Question

I want to store my uploaded images urls to Firestore as list.

Also I'm trying store multiple images for profile. This is how I am storing images. If there is any better way to do that please let me know.

await _firebaseFirestore.collection("noktalar").doc().set({

      'aciklama': aciklama,
      'lat': 123,
      'long': 123,
      'mailAdresi': mailAdresi,
      'noktaAdi': noktaAdi,
      'telefon': tel,
      'webAdresi': webAdresi,
      'yetkiliAdiSoyadi': yetkili,
      'resimler': FieldValue.arrayUnion(resimler)
    });

and I tried this also

     'resimler': imagesUrls.map((value) => value.toJson()).toList(),

Answer 1

You can basically store image URLs as a Strings and when you'll get them in code, you can just use split method to make list from String. That's pretty easy method to solve this problem

Answer 2

You can follow the below steps:

1. First upload your image to Firebase Storage and get the download URL.
2. Now you have the download URL and you can Upload your Enter object to Cloud FireStore with the url.

You can use the below function to get the download url of uploaded image and then store them in a location in Firestore.

Future<String> uploadImage(var imageFile ) async { 
    StorageReference ref = storage.ref().child("/photo.jpg");
    StorageUploadTask uploadTask = ref.putFile(imageFile); 
    var dowurl = await (await uploadTask.onComplete).ref.getDownloadURL();
    url = dowurl.toString(); 
    return url;
 }
