[ionic4] How to close FAB button in ionic4

Thanks dear… but the solution given in the link is not working for me @lucasbasquerotto … This is the code I have written in ts file to close the FAB button : document.getElementById('fab-btn').classList.remove('fab-button-close-active'); document.getElementById('fab-list').classList.remove('fab-list-active'); document.getElementById('fab-btn1').classList.remove('fab-button-show'); document.getElementById('fab-btn2').classList.remove('fab-button-show');
