Dynaimc Branding footer

Dynamic branding footer can be added to widgets that can be added to off-stage widgets.

ℹ️ This branding footer (brandTag parameter) is currrently available only on offStage method. For click method, it'll be added soon.

Branding footer can be added like this.

                await DavinciCapture.offStage(
                  context: context,
                  const PreviewWidget(),

                  /// Footer can be dynamically added for offStage Widgets
                  brandTag: BrandTagConfiguration(
                    padding: const EdgeInsets.only(left: 20, right: 20),
                    decoration: const BoxDecoration(color: Colors.black),
                    leading: const Text(
                      "Footer dyamically added, Inspired from Reddit",
                      style: TextStyle(fontSize: 14),
                    ),
                    trailing: const Icon(
                      LineIcons.redditAlien,
                      color: Color(0xffFF4500),
                    ),
                  ),
                );

---

By default the generated image name will be "davinci". But if you wish to change it, you can pass the image name in DavinciCapture.click method.

await DavinciCapture.click(context: context, imageKey, fileName: "Hello");

---

When the image is captured, you can either open the image preview or get the image in Uint8List.

await DavinciCapture.click(context: context, imageKey, fileName: "Hello", openFilePreview = false, returnImageUint8List = true);

---

If the captured image is pixelated, calculate the pixel ratio dynamically based on the device and pass it to the DavinciCapture.click method.

double pixelRatio = MediaQuery.of(context).devicePixelRatio;

await DavinciCapture.click(context: context, imageKey, fileName: "Hello", pixelRatio: pixelRatio);

---

To save the image directly to the device, set saveToDevice flag to true. You can also specify the album name or you can leave it undefined.

await DavinciCapture.click(context: context, imageKey, fileName: "Hello", saveToDevice = true, album: "Davinci", openFilePreview = false);

---

ℹ️ All the parameters in the click method is present in offStage method too.

🛎️ Note :

• If you wish to save the generated images locally, do remember to add necessary permissions in info.plist and AndroidManifest.xml.
