Dynamically updating options in Uppy plugins, uppy.getPlugin(x).setOptions()

Hi, Everyone

I want the UPLOAD button to show through some kind of boolean flag.

Directly setting up hideUploadButton={true || false} will work as fine. But, when I try to use it through expression it doesn’t work. The flag used for hideUploadButton state changes but no changes occur in Dashboard.

hideUploadButton={!contentID}

    <Dashboard
      uppy={this.uppy}
      plugins={[]}
      inline={true}
      proudlyDisplayPoweredByUppy={false}
      showProgressDetails={true}
      hideUploadButton={!contentID}
    />

When a User selects an Option from the select box then only the upload button should appear. Else no

1. By default selectedContentID will be null. If it’s null then the Upload button shouldn’t appear.
2. When a user selects an option from the select box, the state changes and selectedContentID will set, then Upload button will appear.

Even when the props value gets changed the Dashboard component isn’t re-rendering??

        <Dashboard
          uppy={this.uppy}
          plugins={[]}
          height={100}
          metaFields={[{ id: 'name', name: 'Name', placeholder: 'file name' }]}
          proudlyDisplayPoweredByUppy={false}
          showProgressDetails
          hideUploadButton={!contentID} // <==== value gets changed but Component doesn't re-render
          showLinkToFileUploadResult={false}
          note={!contentID ? 'Please select a content topic from dropdown' : ''} // same here
        />

The contentID might be null or will have some number. Even when the contentID gets changed from null to number, The <Dashboard /> doesn’t re-render?

It’s not possible right now to change plugin options like hideUploadButton after the plugin is installed. We should throw an error in the React components if a prop like that changes.

We may implement a uppy.getPlugin(x).setOptions() method in the future that can deal with this problem.
