# getfflag

Reads the current value of a Roblox Fast Flag.

```luau theme={null}
getfflag(name: string): any
```

Pass the flag's literal name, without a prefix (e.g. `"EnablePreloading"`, not `"DFFlagEnablePreloading"`).

Flag names follow one of six type prefixes: `FFlag` / `DFFlag` (booleans), `FInt` / `DFInt` (integers), `FString` / `DFString` (strings). The leading `D` marks dynamic flags, which refresh at runtime; the rest lock at session start.

## Parameters

| Parameter | Type     | Description |
| --------- | -------- | ----------- |
| `name`    | `string` | Flag name.  |

## Returns

Return type tracks the flag's declared type:

| Flag prefix             | Returns   |
| ----------------------- | --------- |
| `FFlag` or `DFFlag`     | `boolean` |
| `FInt` or `DFInt`       | `number`  |
| `FString` or `DFString` | `string`  |
