💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0

casts and bare as casts in all fromJson factories with explicit typed accessors. Parse errors now surface at construction time via a descriptive FormatException that includes the field name, rather than deferring until element access. All ten type files (das_types, enhanced_types, zk_types, wallet_types, webhook_types, rpc_v2_types, auth_types, staking_types, priority_fee_types, smart_transaction_types) have been migrated. The public API is unchanged.

Replace dynamic with Object? across lib source files; remaining dynamic usage is only in test matcher API signatures required by the test package.
