implement optional import of flutter_libsparkmobile
✓ Specific, descriptive subject✓ Names a concrete action or component! No meaningful explanatory body
What changed, and why it matters
This commit refactors how the Stack Wallet app uses the Firo Spark cryptography library. Instead of directly importing flutter_libsparkmobile everywhere, it introduces a generated interface wrapper so the library can be optionally included or excluded at build time. Most of the diff is code reformatting and replacing direct library calls with calls through the new wrapper. There is no obvious security bug in the diff itself, but the change touches sensitive wallet code (address generation, transaction signing, coin identification, fee estimation) and the generated template has placeholder error paths when Firo is not enabled.
Recommended action
Reviewers should verify that the generated wrapper faithfully forwards all parameters and return values to flutter_libsparkmobile without mutation, that the stub fallback cannot be reached in production builds, and that the moved logging bridge does not drop or misclassify security-relevant Spark library errors. Because the diff is dominated by formatting changes, a side-by-side functional-only comparison is recommended.
Security signals we found
01
Refactor of cryptographic library integration for Firo Spark (address generation, transaction creation, fee estimation, coin identification/recovery, tag hashing)
02
Introduction of build-time conditional implementation via code generation template with stub fallback that throws exceptions
03
Removal of direct flutter_libsparkmobile imports from wallet core and UI files; routing through generated interface
04
Logging bridge for Spark library logs moved into generated template
05
Large formatting-only changes make functional diffs harder to review
Evidence from the diff
The change introduces lib/wl_gen/interfaces/lib_spark_interface.dart, an abstract LibSparkInterface, plus a code-generation template tool/wl_templates/FIRO_lib_spark_interface_impl.template.dart that produces a real implementation backed by flutter_libsparkmobile when FIRO is enabled, or a stub that throws ‘FIRO not enabled!’ when disabled. Call sites in firo_cache.dart, firo_cache_writer.dart, spark name UI, spark_interface.dart, and logger.dart are updated to use the wrapper (libSpark, hashTags, etc.) instead of direct LibSpark/Log imports. The commit also removes the spark-specific logging extension from logger.dart and moves it into the generated template. The pubspec.lock change is a minor transitive dependency bump (build_cli_annotations 2.1.0 -> 2.1.1).
