My 2 year daughter habit is not easy to make her eat any launch, dinner.... how to make her eat a lot ? someday she not get enough food....

Re-examine the issue: My expectation for feeding at that age is 3-5 good feeding days a month & the rest nibbling or grazing.There interest also shifts to carbohydrates to sustain activity rather than protein to sustain growth. Feed at the table & be sure appetizing food is always available in a for they could sample. As long as the growth rate & activity level are normal, relax.Think balanced week not balanced meal.
