Narrative:

After takeoff from ZZZ1 during flap retraction; we got an EICAS message and warning light. Leading edge flap asymmetry; leading edge flap light; and flap indicator stuck in position between 1 and up. We kept our speed at 240 KIAS and a maximum altitude of FL200. Talked to dispatch; maintenance. Decided to continue to ZZZ2 considering WX and increase fuel burn. Requested longest runway in ZZZ2 and emergency equipment; did a cabin advisory; and due to high approach speed and the possibility of additional flap problems; we declared an emergency with ZZZ2 approach control. Normal landing was made; full length rollout; brake temperature was normal; so we taxied to gate.
