Parse amount from ETH QR string in the Send To view

[driquelme]

Description

Currently, Metamask mobile does not extract the amount from an ETH QR string that contains the price in addition to the address in the Send To view. It would be convenient for the amount to be pre-populated so that the user does not have to enter it manually. Usually, these values are very complicated, and it's cumbersome and difficult to enter them correctly.

Technical Details

• Modify QR scanning code to parse the amount in an address string that contains this value. An example of such string could look like this ethereum:<address>[?value=<value>].

Acceptance Criteria

• When scanning an ETH QR code that includes the amount, this value has to be automatically populated in the UI where the amount is currently entered.

Scenario:

• GIVEN a QR code that encodes an amount
• WHEN a user scans the QR, the value appears pre-populated in Metamask in the screen where it has to be entered by the user.
• AND user does not need to enter an amount to send the transaction
