|
## Context
|
|
|
|
- When user tap PDF attachment inside email web, the attachment should be automatically opened in new tab
|
|
- The attachment button in web at the moment can be tapped on itself, and also at the download icon inside it
|
|
- The behavior when tapping either of those places are the same
|
|
|
|
## Decision
|
|
|
|
Separate the business logic of both tappable places:
|
|
|
|
1. When download icon is tapped
|
|
|
|
- Create download anchor and click on it programmatically, triggering the download action of the browser
|
|
- After the browser download the file, browser will handle the file by its own settings & policies
|
|
|
|
2. When anywhere else inside the attachment button is tapped
|
|
|
|
- If attachment is PDF, trigger window.open from html.dart with `_blank` parameter so that the file is opened in new tab
|
|
- If attachment is not PDF, treat the action as if the download icon is tapped as case 1
|
|
|
|
## Consequences
|
|
|
|
- Different behaviors will be triggered depends on where user taps inside the attachment button on Twake Mail web
