I have this issue when try to start printing image A value of type 'Image?' can't be assigned to a variable of type 'Image'. This is my piece of code, someone can help me! Please

Hello @3rdfloordesign, the reason for the error described in the image is that it may be null. add the null safety treatment

final Image? image = decodeImage(bytes); or final Image image = decodeImage(bytes)!;
