Preloader / Spinner React Component

Examples

import React from 'react';
import { Page, Navbar, Block, BlockTitle, Col, Preloader, f7 } from 'framework7-react';
import './preloader.css';

export default () => {
  const openIndicator = () => {
    f7.preloader.show();
    setTimeout(() => {
      f7.preloader.hide();
    }, 2000);
  };
  const openDialog = () => {
    f7.dialog.preloader();
    setTimeout(() => {
      f7.dialog.close();
    }, 2000);
  };
  const openCustomDialog = () => {
    f7.dialog.preloader('My text...');
    setTimeout(() => {
      f7.dialog.close();
    }, 2000);
  };
  return (
    
      
    <Page>
      <Navbar title="Preloader"></Navbar>
      <Block>
        <p>
          How about an activity indicator? Framework7 has a nice one. The F7 Preloader is made
          with SVG and animated with CSS so it can be easily resized.
