How to open email client with React Native?

To open email client with React Native, we call Linking.openURL to open the email address with the mailto URL.

For instance, we write

<Button
  onPress={() => Linking.openURL("mailto:support@example.com")}
  title="support@example.com"
/>;

to call Linking.openURL with the email URL.

Also, we can call it with a subject and body by writing

<Button
  onPress={() =>
    Linking.openURL(
      "mailto:support@example.com?subject=SendMail&body=Description"
    )
  }
  title="support@example.com"
/>;

We just add the subject and body into the URL as query parameters.
