st.title("Streamlit-react-jsonschema Example")
with st.expander("source code of the example pydantic class", expanded=True):
    codes = inspect.getsource(SomeClass)
    st.code(codes)

value, submitted = srj.pydantic_form(model=SomeClass)

st.subheader("result:")
st.write(f"submitted: {submitted}")
st.write(f"type of the result: {type(value)}")
st.write(value)
