    .Share(); // opens the native share sheet immediately
```

--------------------------------

### Add Texture2D Directly

Source: https://context7.com/yasirkula/unitynativeshare/llms.txt

Use AddFile with a Texture2D to save and share it. The format (PNG or JPEG) is determined by the filename extension. Non-readable textures are handled automatically.

```csharp
// Share a screenshot captured this frame
IEnumerator TakeScreenshotAndShare()
{
    yield return new WaitForEndOfFrame();

    Texture2D screenshot = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
    screenshot.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
    screenshot.Apply();

    new NativeShare()
        .AddFile(screenshot, "screenshot.jpg")   // saved as JPEG
        .SetSubject("My Score")
        .SetText("I just hit a new high score!")
        .SetCallback((result, target) =>
        {
            Debug.Log($"Share result: {result}, app chosen: {target}");
        })
        .Share();

    Destroy(screenshot); // avoid memory leak
}
```

--------------------------------

### NativeShare.AddFile (filePath)

```csharp
new NativeShare()
    .SetText("Hello World!")
    .SetCallback((ShareResult result, string shareTarget) =>
    {
        switch (result)
        {
            case ShareResult.Shared:
                Debug.Log($"Shared successfully via: {shareTarget ?? "unknown"}");
                // Check if user picked Twitter
                if (shareTarget != null && shareTarget.ToLowerInvariant().Contains("twitter"))
                    Debug.Log("Shared to Twitter!");
                break;
            case ShareResult.NotShared:
                Debug.Log("User cancelled sharing.");
                break;
            default:
                Debug.Log("Share result unknown.");
                break;
        }
    })
    .Share();
```

--------------------------------

### Set Shared URL

Source: https://context7.com/yasirkula/unitynativeshare/llms.txt

```csharp
new NativeShare()
    .SetText("Check out this game!")
    .SetUrl("https://example.com/mygame")
    .Share();
```

--------------------------------

### NativeShare.Share

Source: https://context7.com/yasirkula/unitynativeshare/llms.txt

```APIDOC
## `NativeShare.SetCallback(ShareResultCallback callback)`

### Description
Registers a callback invoked after the share sheet is dismissed. The callback receives a `ShareResult` enum value and the package/class name of the app the user selected (may be null).

`ShareResult` values:
- `Unknown` — cannot determine outcome
- `Shared` — user selected an app (content was likely shared)
- `NotShared` — user dismissed the share sheet without selecting an app

### Method Signature
`NativeShare.SetCallback(ShareResultCallback callback)`

### Parameters
#### Path Parameters
- **callback** (ShareResultCallback) - Required - The callback function to execute after sharing.

### Example
```csharp
new NativeShare()
    .SetText("Hello World!")
    .SetCallback((ShareResult result, string shareTarget) =>
    {
        switch (result)
        {
            case ShareResult.Shared:
                Debug.Log($"Shared successfully via: {shareTarget ?? "unknown"}");
                // Check if user picked Twitter
                if (shareTarget != null && shareTarget.ToLowerInvariant().Contains("twitter"))
                    Debug.Log("Shared to Twitter!");
                break;
