Clear the text in text_input

Using Streamlit
8

For posterity and hoping to help others, a working example form with clear button and callback that clears input fields:

import streamlit as st

def clear_form():
    st.session_state["foo"] = ""
    st.session_state["bar"] = ""
    
with st.form("myform"):
    f1, f2 = st.columns([1, 1])
    with f1:
        st.text_input("Foo", key="foo")
    with f2:
        st.text_input("Bar", key="bar")
    f3, f4 = st.columns([1, 1])
    with f3:
        submit = st.form_submit_button(label="Submit")
    with f4:
        clear = st.form_submit_button(label="Clear", on_click=clear_form)

if submit:
    st.write('Submitted')

if clear:
    st.write('Cleared')
