Post Image Update

Post.ts

// When the app restarts or when loading the posts from firestore do this

// import the ImageUpload class like you are doing in the posts screen

// check if a post is missing a picture

if (post.picture.uri == undefined || post.picture.uri == "" ) {
  // if a post is missing a picture then get the picture locally via the post id
  const picture = await ImageUpload.getLocalPic(post.Id);
  
  // get the pic preview too
  const preview = await ImageUpload.preview(picture);
  
  // then upload the image again but pass undefined as the post id because we don't want to save the picure again
  const url = await ImageUpload.upload(picture, undefined);
  
  // then update the the post in firebase using the post id
   const ref = Firebase
        .storage
        .ref()
        .child(post.id);
  
  // update the post object
  
  const post: Post = {
    id: post.id,
    url,
    preview,
    // set the rest of the params
  };
  
  const snapshot = await ref.put(post);
   
  
  // finally delete the image locally
  await ImageUpload.deletePictureLocally(post.id);
  
  // and then you will be done :)
