fromJson static method

DriverCapabilities fromJson(
  1. Map<String, Object?> json
)

Parses a driver-capabilities JSON map from the native layer.

DatabaseType is taken only from the canonical engine field. An unknown engine stays DatabaseType.unknown even if driver_name would match the legacy heuristic.

Implementation

static DriverCapabilities fromJson(Map<String, Object?> json) {
  final driverName = json['driver_name'] as String? ?? 'Unknown';
  final engineId = json['engine'] as String? ?? DatabaseEngineIds.unknown;
  return DriverCapabilities(
    supportsPreparedStatements:
        json['supports_prepared_statements'] as bool? ?? true,
    supportsBatchOperations:
        json['supports_batch_operations'] as bool? ?? true,
    supportsStreaming: json['supports_streaming'] as bool? ?? true,
    maxRowArraySize: (json['max_row_array_size'] as num?)?.toInt() ?? 1000,
    driverName: driverName,
    driverVersion: json['driver_version'] as String? ?? 'Unknown',
    databaseType: DatabaseType.fromEngineId(engineId),
    engineId: engineId,
    supportsNativeBcp: json['supports_native_bcp'] as bool? ?? false,
  );
}
