Were is used with plural pronouns
The kids were hungry.
And we can add "None of":
None of the kids were hungry.
But I read a lot of articles and books use "was" with "None of":
None of the kids was injured.
None of them was so unconcerned about the state…
At that time none of the men was being troubled …
So, in formal english, What should we use with "none of"? "was" or "were"?

Both sentences are grammatical.
When you use the phrase "none of" in front of a plural noun or pronoun, you can use either a singular or plural form of a verb.
However, the plural form is common both in formal and in informal English. The singular form is formal and isn't much used.
Besides, if there's an uncountable noun or a singular pronoun in front of the "none of", you use a singular form of a verb after it (The Free Dictionary). For examples:
None of the wheat was ruined.
Yet none of this has seriously affected business.
