Accepted

Context

For large images (several MB or more) converting to base64 will take a long time and exceed the storage limit of the string. Leads to long waits on the main thread, causing a feeling of not being smooth on mobile devices with weak configuration.

Decision

We can reduce the image size and quality when displaying.

• For mobile:
  • Use flutter_image_compress to compress image use native (Objective-C/Kotlin) with faster speed.

Consequences

• The size of the image has been significantly reduced with the display quality not much different from the original image.
• Faster processing speed.
