React redirect/push from Next lifecycle at event handler from class-based component

I need to make a redirect from inside an onSubmit call.

Currently the full code is as below, and I need to keep CampaignNew as a class-based component. How can I do it?

import React, { Component } from 'react';
import Layout from '../../components/layoyt';
import { Form, Button, Input, Message } from 'semantic-ui-react';
import factory from '../../components/factory';
import web3 from '../../components/web3';

class CampaignNew extends Component {
    state = {
        minimumContribution: '0',
        errorMessage: '',
        loading: false
    };

    onSubmit = async (event) => {
        event.preventDefault(); // Prevent the browser to attemp submission at initialization

        this.setState({ loading: true, errorMessage: '' });

        try {
            await window.ethereum.enable();
            const accounts = await web3.eth.getAccounts();
            console.log('Account :' + accounts[0]);

            await factory.methods
                .createCampaign(this.state.minimumContribution)
                .send({
                    from: accounts[0]
                });

            //// !!PUSH_TO_('/')

            this.setState({ loading: false });

        }
        catch (err) {
            this.setState({ errorMessage: err.message });
            this.setState({ loading: false });
        }

    };

    render() {
        return (
            <Layout>
                <h3>
                    Create a Campaign
                </h3>
                <Form onSubmit={this.onSubmit} error={!!this.state.errorMessage}>
                    <Form.Field>
                        <label>Minimum Contribution</label>
                        <Input label='wei'
                            labelPosition='right'
                            value={this.state.minimumContribution}
                            onChange={event => this.setState({ minimumContribution: event.target.value })}
                        />
                    </Form.Field>

                    <Message error header='There was some errors with your submission' content={this.state.errorMessage} />
                    <Button loading={this.state.loading} primary>Create</Button>
                </Form>
            </Layout>
        );
    }
}

export default CampaignNew;
