。
She grew up just as we hoped.
Literal
She [topic-は] our expectations [in accordance with-通りに] grew-up.
The suffix 通り (どおり after a noun) means 'in accordance with / exactly as,' attached here to 期待 ('expectations'). The adverbial 期待通りに ('as expected, as hoped') is a common stock phrase. Note that the kanji 通 — 'pass through, traffic' — can read very differently in different compounds: とおり as a free noun ('street, way of doing things'), どおり as this suffix, 通る (とおる) as a verb ('pass through'), 通学 (つうがく) as a Sino-Japanese compound ('commuting to school'). One kanji, many lives.
