React Hooks with React Router v4 - how do I redirect to another route?

Your problem is related to Programmatically navigating using react-router-v4 instead of with hooks,

In react-router-v4, you would get history from props if the Todos component is rendered as a child or Route or from an ancestor that is render form Route and it passed the Router props to it. However it is not receiving Router props, you can use withRouter HOC from react-router to get the router props and call props.history.push(destUrlEdit)

import React, {useState, useContext, useEffect} from 'react';
import TodosContext from './context'
import { withRouter } from 'react-router-dom';

function Todos(props){   
    const [todo, setTodo] = useState("")
    const {state, dispatch} = useContext(TodosContext)
    useEffect(()=>{
        if(state.currentTodo.text){
            setTodo(state.currentTodo.text)
        } else {
            setTodo("")
        }
        dispatch({
            type: "GET_TODOS",
            payload: state.todos
        })
    }, [state.currentTodo.id])

    const editRow = event =>{
        let destUrlEdit = `/todos/${event.id}`

        let obj = {}
        obj.id = event.id
        obj.text = event.text

        dispatch({type:"SET_CURRENT_TODO", payload: obj})

        //after dispatch I would like to redirect to another route to do the actual edit
        //destUrlEdit
        props.history.push(destUrlEdit);
    }
    return(
        <div>
            <h1>List of ToDos</h1>
            <h4>{title}</h4>
            <ul>
                {state.todos.map(todo => (
                    <li key={todo.id}>{todo.text} &nbsp;
                        <button onClick={()=>{
                            editRow(todo)}}>
                        </button>
                    </li>
                ))}
            </ul>
        </div>
    )
}

export default withRouter(Todos);

You can use UseNavigate to move the change page. here is the sample example

"react-router-dom": "^6.2.1",

// Route File
import React, { Suspense, lazy } from "react";
import { BrowserRouter, Routes, Route } from "react-router-dom";
import IndexLayout from "../layouts";
import NotFoundPage from "../views/404";
import Loader from "../components/Loader";

const Dashboard = lazy(() => import("../containers/DashboardContainer"));

const Router = () => {
  return (
    <BrowserRouter>
      <IndexLayout> // this one is kind of HOC
        <Routes>
          <Route
            path="/"
            element={
              <Suspense fallback={<Loader />}>
                <Dashboard />
              </Suspense>
            }
          />

</end every thing>
// any component

import React, { useEffect } from "react";
import { useNavigate } from "react-router-dom";

const TestComponent = ({ newSignup }) => {
    const navigate = useNavigate();
    
    useEffect(() => {
        if (newSignup) {
          navigate("/login");
        }
      }, [newSignup]);
    return (
        <div>
            
        </div>
    )
}

export default TestComponent

It's actually a lot simpler than the other answers, React Router v5.1 provides a useHistory hook.

import React from 'react'
import { useHistory } from 'react-router-dom'

const MyComponent = () => {
  const history = useHistory()
  const handleButtonClick = (event) => {
    history.push(event.target.value)
  }
  return (
    <button
      type="button"
      value="/my/path"
      onClick={handleButtonClick}
    >
      Navigate Me!
    </button>
  )
}
