In some situations you might want to prefill some fields for the user. This can be achieved by the following method.

cordova.plugins.GleapPlugin.preFillForm({
  description: "This text will be prefilled.",
  errordescription: "This text will be prefilled as well.",
  someformidentifier: "This text will also be prefilled.",
});

You need to pass a key value pair to the preFillMethod. The key is the form identifier, which can be found under the ‘Advanced’ section of a question. (see screenshot for an example)
