Intermittent Issue with Multiple Signatures: Duplicate Saved Signatures

[oussamakh96]

Description:
Hello,

I encountered an issue when working with react-native-signature-canvas. In my use case, I have two signature canvases that need to be signed and validated simultaneously.

Occasionally (about 1 in 4 times), when saving both signatures, the same signature gets saved for both canvases, even though they are distinct.

I suspect the issue might be related to how the component handles unique identifiers for the saved signature data (e.g., filenames or temporary storage paths). Could you confirm if this is a known issue, or if there’s a workaround to prevent this conflict?

Steps to Reproduce:

Render two signature canvases simultaneously in a screen.
Sign both canvases with different signatures.
Save both signatures (e.g., using onOK callback or similar).
Observe that, in some cases (approximately 1/4 times), the saved signatures are identical.
Expected Behavior:
Each signature canvas should save its unique signature without overwriting or duplicating the other.

Thank you for your help and for maintaining this library!
