Question 1

How to export a drawing as an image in react-native-sketch?

Accepted Answer

Call the save() method on the sketch instance, which returns a promise with the image path. For example, this.sketch.save().then(image => console.log(image.path)). You can set the image type via the imageType prop to PNG or JPG.

Question 2

Is react-native-sketch compatible with Android?

Accepted Answer

No, it's only available for iOS, as the README states the author lacks Android development knowledge. This makes it unsuitable for cross-platform projects without significant modifications or alternatives.

Question 3

React native sketch vs react-native-signature-capture for drawing?

Accepted Answer

React Native Sketch is a general-purpose drawing component with features like stroke customization and image export, while react-native-signature-capture is more focused on signature capture. However, react-native-sketch is unmaintained, so for production use, consider actively maintained libraries.

Question 4

Can I use react-native-sketch with Expo without ejecting?

Accepted Answer

No, you must detach to ExpoKit because it requires native iOS code linking. The README explicitly notes this limitation, adding setup complexity for Expo users.

Question 5

What are the known bugs in react-native-sketch?

Accepted Answer

The main known bug is screen rotation causing weird behavior, as mentioned in issue #23. Since the project is unmaintained, other issues might remain unresolved, such as compatibility with newer React Native versions.

Question 6

How to change stroke color dynamically while drawing?

Accepted Answer

Update the strokeColor prop in real-time during drawing. The component supports on-the-fly customization, allowing users to switch colors without clearing the canvas, as demonstrated in the features.
