The equivalent to Android’s density buckets are:
| Android density qualifier | Flutter pixel ratio |
|---|---|
| ldpi | 0.75x |
| mdpi | 1.0x |
| hdpi | 1.5x |
| xhdpi | 2.0x |
| xxhdpi | 3.0x |
| xxxhdpi | 4.0x |
Flutter follows a simple density-based format like iOS. Image assets might be 1.0x, 2.0x, 3.0x, or any other multiplier. The so-called devicePixelRatio expresses the ratio of physical pixels in a single logical pixel.
images/my_icon.png // Base: 1.0x image
images/2.0x/my_icon.png // 2.0x image
images/3.0x/my_icon.png // 3.0x image
