It is not linear, it is bent and the ideal angle is 109.5
Lewis structures do not tell you anything about molecular geometry you have to invoke hybridisation argumments or us VSEPR (AXE theory) to make predictions
Sulphur difluoride is the chemical name for the molecular formula SF2. SF2 can be represented by the Lewis dot structure of: .. .. ..:F : S: F: .. .. ..
SF2 is a molecular solid. It is a nonpolar molecule held together through london dispersion intermolecular forces.

SF2
Yes. SF2 is nonpolar due to the fact that the difference in electronegativity between the two atoms in each bond is 1.4.
The central atom has two lone pairs and two shared pairs, so the molecular shape is v-shaped (like H2O). Since F has a much higher electronegativity than S, the electron density in this molecule is shifted away from the sulfur and toward the center of the two fluorines. So the molecule has a dipole moment. This molecule is a good example of why you must draw the Lewis structure before determining molecular shape. With a casual glance this molecule may appear to be linear, but the Lewis structure looks like this
