Modern JSON Handling in a Macro-less Flutter Era
summary
Compares manual JSON methods, json_serializable generated code, and freezed data classes, demonstrating concrete patterns like using top-level converters for yes/no booleans and seconds-from-epoch DateTime, and recommending includeIfNull: false plus null-coalescing defaults. Describes the practical promise of augmentations to attach fromJson/toJson to external types and to spread implementations across files. Gives actionable build_runner tips: use --watch, optionally --delete-conflicting-outputs, exclude .g.dart from analyzer, and decide whether CI should run generation.
