I'm using final-form
and final-form-material-ui
I want to set min and max values for number inputs. Already tried
InputProps={{ inputProps: { min: 0, max: 10 } }}
but it doesn't work.
Also I want to add seconds for preparation_time
so the format would be 00:00:00.

using the documentation: https://final-form.org/docs/react-final-form/examples/field-level-validation
sandbox demo: https://codesandbox.io/s/wizardly-paper-2dtwf?file=/src/App.js:3139-3391
write your validation in this way:
const minValue = (min) => (value) =>
isNaN(value) || value >= min ? undefined : `Should be greater than ${min}`;
const composeValidators = (...validators) => (value) =>
validators.reduce((error, validator) => error || validator(value), undefined);
then use the validation in this way:
<Field
name="no_of_slices"
component={TextField}
type="number"
validate={composeValidators(minValue(18))}
label="Number of slices"
/>
