      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,

              .then((imageDate) => {
                let base64image = 'data:image/jpeg;base64,' + imageDate;
                this.photo = base64image;
                // this.userService.uploadToStorage(this.user.user_id, this.photo, 'citizens')
                this.uploadInformation(this.photo);
                console.log(this.photo)
              }, (error) => {
                console.log(error)
              })
              .catch((error) => {
                console.log(error)
              })
  }

    uploadInformation(info) {
     let upload = this.userService.uploadToStorage(info);
     upload.then().then(res => {
       this.userService.storeInfoToDatabase(this.user.key, res.metadata)
         .then(() => {
           alert('Inserido com sucesso so colocar o toast depois')
         })
     })
   }

Now in my service I have this code and the storeInfoToDatabase method received 2 parameters user.key and image name service.ts

uploadToStorage(information: any): AngularFireUploadTask { 
    let newName = information +'.png'; 
    return this.afs.ref(`users/citizens/${newName}`).putString(information, 'base64');
  }

  storeInfoToDatabase(user_id, metainfo) {
    let toSAve = { 
      url: metainfo.downloadURLs[0],
      fullPath: metainfo.fullPath,
      contentType: metainfo.contentType,
    } 
    return this.db.list(`${this.PATH}/citizens`).update(user_id, (toSAve))
  }
