Black bar on keyboard top Ionic v4

Input field is hiding under keyboard when keyboard open, for that i just tried removing the plugin
and added like below.
cordova plugin add cordova-plugin-ionic-keyboard
npm install @ionic-native/keyboard
issue is resolved and input is coming above the keyboard, but getting black bar over the keybaord.
Please suggest the solution.
