need resizeImage more option

image_cache_manager.dart

line 89:
var resizeFactor = max(resizeFactorHeight, resizeFactorWidth);

Get the maximum compression ratio here, which will make the picture very blurry. eg:
rawImage size: 300 x 1000
display size: 50 x 50
resize: 15 x 50

Then the width of the display on the interface will stretch, and the picture will look terrible.

Can an option be enabled for the developer to decide how to resize? For example, change the code to the following
var resizeFactor = min(resizeFactorHeight, resizeFactorWidth);

从 image_cache_manager.dart 第 89 行开始，追踪 resizeFactorHeight 和 resizeFactorWidth 如何确定缓存图像的尺寸。定义 issue 所要求的面向开发者的调整大小选项，然后验证 300 x 1000 与 50 x 50 的示例能够避免过度模糊和不必要的拉伸。
