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(imageKey, fileName: "Hello");
When the image is captured, you can either open the image preview or get the image in Uint8List.
await DavinciCapture.click(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(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(imageKey, fileName: "Hello", saveToDevice = true, album: "Davinci", openFilePreview = false);
click method is present in offStage method too.
🛎️ Note :
- Cannot capture Platformview due to issue flutter/flutter#25306
- If you wish to save the generated images locally, do remember to add necessary permissions in
