final

The native symbol to be resolved, if not using the default.

If not specified, the default symbol used for native function lookup is the annotated function's name.

Example:

@Native<Int64 Function(Int64, Int64)>()
external int sum(int a, int b);

Example 2:

@Native<Int64 Function(Int64, Int64)>(symbol: 'sum')
external int sum(int a, int b);

The above two examples are equivalent.

Prefer omitting the symbol when possible.

Implementation

final String? symbol;
