The widget takes much time to be shown about filestack-react HOT 2 CLOSED

@yhjor sorry for the late response.
If you are looking for functions like onOpen, onFileUploadProgress to have full control of the entire steps you just need to pass them in the options parameter.

For your reference, take a look at the official documentation example (https://www.filestack.com/docs/javascript-api/picker-examples-v3):

client.pick({
  uploadInBackground: false,
  hideWhenUploading: true,
  startUploadingWhenMaxFilesReached: true,
  onFileUploadProgress: function(file, progressEvent) {
    console.log(JSON.stringify(progressEvent.totalPercent))
  }
}).then(function(result) {
  console.log(JSON.stringify(result.filesUploaded))
})

from filestack-react.

As wrote @samuxyz it can be done by passing specific properties to the options object.

More about possible picker options you can find in our docs:
