[image_picker] image file in gallery is deleted by image_picker if it was scaled

[microdog]

When picking an image from the gallery using the image_picker plugin, the image file in the gallery is deleted by image_picker if the image is scaled(exceeds the maxWidth or maxHeight limit).

It seems that this issue was introduced in flutter/plugins#1288 which was intended to delete the original image captured from the camera(#23500), but the patch forgot to check the image source.

Steps to Reproduce

1. use the image_picker plugin: 0.5.0+9 (issue introduced in 0.5.0+6)
2. just write a simple demo to pick an image from the gallery with maxWidth and maxHeight set.
3. pick an image from the gallery which exceeds the maxWidth and maxHeight limit.
4. Boom. The original image file just vanished.

Not all devices are affected by this issue. If the resolved file path is scoped in the Android app package, it is ok to delete the file. But the resolved file path on many of our test devices points to the original image file, for example, in /storage/emulated/0/DCIM/Camera. It seems that some devices refuse to delete the file.

Some of our devices affected:

• OnePlus 6(A6000) - Android 9(OP6_H2_BETA_17, A6000_22_190309)
• Xiaomi MI 8 - Android 9(MIUI 10.2.2.0)

Some of our devices NOT affected:

• Pixel 2 XL - Android 9(PQ1A.190105.004)
• Xiaomi MI 5s Plus - Android 8(MIUI 10.2.1.0)

I forked the plugins and did a temporary fix. You can use my fork temporary

image_picker:
    git:
      url: git://github.com/tlcheah2/plugins.git
      path: packages/image_picker

Any update on this? The PR was created a week ago but no feedback was received.

Some other image_picker issues caused by "file not found" error may also be caused by this issue because the user can select an image from the gallery whose file has already been deleted.

This should be fixed in flutter/plugins#1445.
