When identifying minerals, having no streak is a property of hardness. A streak plate has a hardness of ~7(Moh's Scale). Thus any mineral having a hardness greater than 7 will have no streak.
Metallic is the description of luster. Or the general appearance of a mineral surface in reflected light.
If you were refering to the mineral having metal elements in it, streak is actually very useful for identifying them. Many minerals that are composed of non-metals have a white streak which can appear to be no streak, however there are also many minerals with no streak which are composed of non-metallic minerals (Diamond).

Why Is Streak A Useful Property For Identifying Minerals?
The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.

What test is best used to distinguish a nonmetallic mineral from a metallic mineral?
One common test to distinguish between nonmetallic and metallic minerals is the streak test. Nonmetallic minerals will typically leave a powder streak of color when rubbed against a white ceramic plate, while metallic minerals will leave a metallic streak.
What is the color of a metallic streak?
The color of a metallic streak is typically a dark gray or black color. This is because the streak left behind by a metallic mineral is the color of the powdered form of the mineral, which is often dark due to the presence of metal atoms.
