what happens when the minValue is bigger than the maxValue?
how about we throw an exception when that happens?

I added the exception. UI will crash when minValue > maxValue, like the slider and date widgets.

Okay, but feel free to speak your thoughts on this, we could for example: show an error message to the user, instead of outright crashing the app. We're open for discussion.

What do you think?

Ig it's rare for a scenario like that to happen. Adheres to the rules, but with nonsensical values.

Alternatively, I view the minValue > maxValue a meaningless constraint on the UI, so it make sense to treat it as though the constraint doesn’t exist? We can set minAnswerValue and maxAnswerValue to null if when that happens.

Looks like the web app https://lhcforms.nlm.nih.gov/lhcforms ignored that scenario

// Update error message if draft answer present
if (questionnaireViewItem.draftAnswer != null) {
textInputLayout.error =
textInputLayout.context.getString(
R.string.integer_format_validation_error_msg,
formatInteger(Int.MIN_VALUE),
formatInteger(Int.MAX_VALUE),
formatInteger(minValue),
formatInteger(maxValue),
)
}
}
