Social sharing in facebook

When I use this below code to share something on another apps and when I click on facebook and then share. After that process It works not fine. In android, message not be prefilled but in IOS message will be prefilled in the post section.

Anyone can tell me whats wrong I do in the code?

this.socialSharing.share("Test message", "Test subject", null, "").then(() => {
      console.log("Share Success");
}).catch(() => {
      console.log("Share Error");
