如何使用 crud 方法将图像文件上传到 FIRESTORE？

Question

I'm currently uploading some data to firestore:

 Map<String, dynamic> ads = {
                      'adTitle': widget.title,
                      'adPrice': widget.price,
                      'adCategory': widget.dropdownValue,
                      'adCondition': this.newCondtionVal,
                      'adDesc': widget.desc,
                      'user_id': uID,
                    
                      ///TODO upload the images.
                    };
                    crudObj
                        .addData(ads)
                        .then((value) => {
                              showInSnackBar("dataAdded"),
                            })
                        .catchError((e) {
                      print(e);
                    });

Images selected via Image_Picker, the question is how can I upload it to firebase using the method mentioned above.
PS: I'm a newbie to Flutter and Firebase stuff.

Answer 1

you can convert your image to base64 and give to the firebase which gives you the getDownloadURL . That getDownloadURL should be saved somewhere so you can access it and show it into your flutter app.

I have a code snippet which you can refer it

Future uploadFile() async {    
   StorageReference storageReference = FirebaseStorage.instance    
       .ref()    
       .child('chats/${Path.basename(_image.path)}}');    
   StorageUploadTask uploadTask = storageReference.putFile(_image);    
   await uploadTask.onComplete;    
   print('File Uploaded');    
   storageReference.getDownloadURL().then((fileURL) {    
     setState(() {    
       _uploadedFileURL = fileURL;    
     });    
   });    
 }  

This is about a firebase real-time database. if you need for firebase database then please let me know.
