I went through similar questions but haven't seen something as simple as my question.
In the online course I am following this example is given:
你在这儿写了很多。
Though, AFAIK the sentence structure is S+t+p+how+Verb(+object) according to the "Chinese Grammar" app. Thus, I would expect the correct sentence to be 你在这儿很多写了, since 很多 clearly is not an object (in fact, falls to the "how" category) and is not supposed to come to the end.
Can somebody clarify this, please? Thank you.
