This is not correct. T1/T2/T3 are connected airside and you can walk between every gate. SIN T4 is in a separate building, and there is an airside bus.
The question is whether your onward airline (from the clues you provided, perhaps it is IndiGo?) offers check in service at a SIN Transfer Desk. If so, you can stay airside (never having entered Singapore). But if not, plan to explore the airside airport facilities for a few hours, and then enter Singapore immigration at perhaps 2-3 am, and proceed to your landside airline checkin counter to check in, and then back airside for your flight.
