Well,if theoretically we say the value of a resistor is zero then will there be any heat dissipation across the resistor(because heat is produced only when there's a resistance to the flow of current.)If there's zero resistance then won't current simply go on flowing?

Yes, if the resistance is zero, voltage drop is null, and all the current the generator can provide flows in the conductor.
This happends for example in SQUIDs (superconductor devices with a circular form), where current has been measured flowing for several months continously because of the near-zero resistance of the device
