[hoangdat]

not a bug. New function

[chibenwa]

I 'd expect it to be a default feature of any text field.

Missing basic expectations is a category of bugs.

Missing basic expectations is a category of bugs.

Agree in some cases. But in an aspect of Flutter, it is not a built-in function for text field.
WE MUST SPEND A LOT OF EFFORT FOR THIS.

NOT A BUG.

[chibenwa]

it is not a built-in function for text field

Regular users expects it to be a built in feature of text fields....

Anyway let's stop arguing and let's plan work on this.

[tddang-linagora]

• Implement super_drag_and_drop, implement TextDropZone
• Integrate TextDropZone into TagEditor
• Integrate TextDropZone into TextFieldBuilder

[hoangdat]

try to test carefully in all platforms and common browsers

[tddang-linagora]

Would break drag & drop for inline images and attachments. Need further investigate.

POC:

• replace desktop_drop dependency with super_drag_and_drop
• handle both case of drag n drop text or file
