st.text_input live update parameter

Problem

In the following code:

import streamlit as st

text = st.text_input('Name')
text

text is only being updated when the user presses enter. This goes against the nature of flow of streamlit where users are able to just see the result live.

Solution

Have st.text_input accept a live parameter. If the live parameter is set to true, then the result is changed as the user types the result and does not need to manually input enter.

Additional context

I volunteer to create this PR, as it should be very quick to implement and PR

Closing this issue as @blackary created a custom component which addresses this need/adding it to the main library would likely cause problems for most users. Feel free to tag us on this issue if you’d like it to be reopened.
