-You can use `Icon.hasIcon(name)` to check if the name is valid in current icon set.
+### Static Methods
+
+| Prop | Description |
+|---|---|
+|**`getFontFamily`**|Returns the font family that is currently used to retrieve icons as text. Usage: `const fontFamily = Icon.getFontFamily()`|
+|**`getImageSource`**|Returns a promise that resolving to the source of a bitmap version of the icon for use with `Image` component et al. Usage: `const source = await Icon.getImageSource(name, size, color)`|
+|**`getRawGlyphMap`**|Returns the raw glyph map of the icon set. Usage: `const glyphMap = Icon.getRawGlyphMap()` |
+|**`hasIcon`**|Checks if the name is valid in current icon set. Usage: `const isNameValid = Icon.hasIcon(name)`|
