hot-fix(fiat-onramp): breaking Ramp API change

[takenagain]

Aligns the Ramp enabledFlows configuration parameter with the format expected and defined in their documentation.

Although incorrect, the Ramp v1 API previously accepted (or ignored) the URL encoded string of a JavaScript array ['ONRAMP'] -> %5B%27ONRAMP%27%5D. A recent change to their form/API appears to have tightened up their validation, and the URL-encoded array is no longer accepted.

Ramp was last tested between 07-15 May 2025 (#2608 , #2570), so this change likely occurred sometime afterwards. I couldn't locate changelogs, or PRs in their repositories documenting releases or major changes.

Note:

• They have also recently updated their excluded countries list, and I can no longer make payments or proceed with KYC.
• Their new form does not play well with ad-blockers when entering a new email (new account without KYC completed).

Summary by CodeRabbit

• Bug Fixes

  • Corrected the format of the payment flow parameter when initiating a fiat-to-crypto purchase, ensuring smoother transaction processing.

• Chores

  • Updated the app version number.

Walkthrough

The changes update the value of the 'enabledFlows' key in a payload within the RampFiatProvider class, altering it from a bracketed string to a plain string. Additionally, the project version in pubspec.yaml is incremented from 0.9.1+0 to 0.9.1+1. No other logic or configuration is modified.

Changes

File(s)	Change Summary
lib/bloc/fiat/ramp/ramp_fiat_provider.dart	Changed 'enabledFlows' value in payload from '[ONRAMP]' to 'ONRAMP'
pubspec.yaml	Incremented version: 0.9.1+0 → 0.9.1+1

Poem

A bracket dropped, the flow set free,
"ONRAMP" stands alone for all to see.
A version bumped, a tidy sweep,
Into the code, these changes creep.
Hop, hop, hooray—release is near,
The rabbit grins from ear to ear!

pubspec.yaml (1)

18-18: Version bump looks appropriate for this bug fix.

The build number increment from 0.9.1+0 to 0.9.1+1 correctly reflects this as a patch-level fix without API changes.

lib/bloc/fiat/ramp/ramp_fiat_provider.dart (1)

312-312: Correctly fixes the Ramp API breaking change.

The change from '[ONRAMP]' to 'ONRAMP' removes the JavaScript array brackets that were incorrectly formatted as a string. This aligns with the PR description and addresses the API validation tightening mentioned in the objectives.

Let me verify there are no other instances of the old format in the codebase:

#!/bin/bash
# Description: Search for any other instances of the old '[ONRAMP]' format or similar patterns
# Expected: Should only find references in comments, documentation, or this fix

echo "Searching for old format '[ONRAMP]' pattern..."
rg -i '\[.?ONRAMP.?\]' --type dart

echo -e "\nSearching for 'enabledFlows' usage..."
rg -i 'enabledFlows' --type dart -A 2 -B 2

echo -e "\nSearching for similar bracket patterns in Ramp-related code..."
rg -i "ramp" --type dart -A 5 -B 5 | rg '\[.*\]'
