Can't deploy firebase cloud function for flutter

Question

Error: Error occurred while parsing your function triggers.

TypeError: require(...) is not a function
    at Object.<anonymous> (A:\Android Projects\buy_storage_try\buy\functions\index.js:21:45)

And this is the line of code:

const gcs = require('@google-cloud/storage')(gcconfig);

What version of @google/cloud-storage are you using, and what documentation are you using that suggests your code should be correct? — Doug Stevenson, Nov 23 '18 at 05:07
@google-cloud/storage@2.3.1 I'm using a video tutorial by Maximilian Schwarzmüller — Adam CJ, Nov 23 '18 at 22:23

Use this instead of gcconfig. Should work just fine.

const projectId = 'your-project-id';
const keyFilename = 'your-keyfile.json';

const {
    Storage
} = require('@google-cloud/storage');

const gcs = new Storage({
    projectId: projectId,
    keyFilename: keyFilename
});

You're using a version of @google-cloud/storage greater then or equal to 2.0.0. The APIs changed in 2.0.0. The tutorial you're following is out of date and was probably written against 1.x.

Look at the documentation for the module. The way to initialize the SDK is like this:

// Imports the Google Cloud client library
const {Storage} = require('@google-cloud/storage');
// Creates a client
const storage = new Storage();
const bucket = storage.bucket();

Thanks so much. was very helpful. Your solution is simple and easy to follow — Adam CJ, Nov 24 '18 at 23:08
