asBlob method

Expr<Uint8List?> asBlob()

Cast as Expr<Uint8List?> using CAST(NULL AS BLOB).

This method is rarely necessary, as you can generally pass toExpr(null) to any method expecting an Expr<Uint8List?>. But in some complex scenarios this can alleviate type inference issues.

Implementation

Expr<Uint8List?> asBlob() => CastExpression._(this, ColumnType.blob);
