Narrative:

I was pilot flying for the leg. It was a flaps 20 takeoff. As we accelerated at 1;000 ft. AGL; I called for flaps 8. We immediately received a 'flaps fail' caution message. The captain ran the QRH and I took the radios. I told ATC we could not go higher than 15;000 ft AGL and were limited to 220 knots. Our first inclination was to continue [flight]; but after further evaluation of our fuel and the QRH; which states land at the nearest suitable airport; we [requested priority] and diverted. I called the flight attendant and told her we would be diverting for a flap malfunction and that there would be fire trucks standing by as a precaution; but that it would be a relatively normal landing. She asked if we would make a passenger announcement. I told her yes. The captain made an announcement to the passengers; and followed up with another call to the flight attendant. The captain took the flight controls and became pilot flying. I took a second look at the QRH to make sure we hadn't missed any steps. I then began to setup the aircraft for a visual approach. We asked for a 15 mile final to be sure we were configured properly for the approach and landing. The captain touchdown smoothly. As we decelerated; we received a left thrust reverser unlocked caution message. We were unable to stow the thrust the thrust reverser. The captain called for the left thrust reverser unlocked QRH. We ran the QRH and elected to shut down the left engine.[my suggestion is to] continue teaching and training the flaps fail scenario in the sim.
