To Reproduce

Use modified example from plugin

Modified example

Create proguard file int android/app/proguard-rules.pro with lines:
To use square plugin in release: -keep class sqip.** { *; }
To see class log error details: -keep class com.ndsthreeds.** { *; }
Config release signin. Add to file android/app/build.gradle this lines:

android { 

// Other configs
    buildTypes {
        release {
            signingConfig signingConfigs.debug
            minifyEnabled true
        }
    }

Modify buy_sheet.dart to use verifyBuyer. Uncomment await _onStartCardEntryFlowWithBuyerVerification(); and comment await _onStartCardEntryFlow();

// call _onStartCardEntryFlow to start Card Entry without buyer verification (SCA)
// await _onStartCardEntryFlow();
// OR call _onStartCardEntryFlowWithBuyerVerification to start Card Entry with buyer verification (SCA)
// NOTE this requires _squareLocationSet to be set
await _onStartCardEntryFlowWithBuyerVerification();

Reproduce error

Start example in release mode flutter run --release
Press button Pay with card
Add card with SCA to payment. Example: 4800 0000 0000 0004 01/23 111 00000. References
Press pay
Error: App crash

Expected behavior

Don't crash app when use minifyEnabled true in release mode

Answer 3 · 2022-12-09T20:39:30.000Z

Hello!
Thank you for flagging this issue, I'm happy to help you with it.

First, some questions:

What version of Android In-App Payments SDK are you using? Latest is 1.5.8; and Flutter plugin might be pulling in an older version (like 1.5.6)
Can you share your build/outputs/mapping/release/mapping.txt file that way we can identify what b.d.d.a.r.a might be? If yes, please use this link to send it safely to me https://squareup.sendsafely.com/u/artem
What does the final (merged) proguard-rules.pro look like? Can you share it as well, please?

Answer 4 · 2022-12-12T06:24:07.000Z

In-App Payments Plugin version: 1.7.4
and 3. Now I don't have time to do this, but when posible I might send the files
