How did the amritsar massacre affect india’s independence movement?

During 1890 to 1920 several British colonies like Canada, Australia, Ireland, New Zealand and South Africa attained Dominion status with self rule govt. India also demanded a similar status without any luck. But with the Amritsar Massacre/Jallianwala Bagh Tragedy in 1919, India did not any longer trust the British and started a Non-cooperation movement until 1922 and subsequently in 1930 passed the Declaration of (Complete) Independence from British.
