addBreakpoint method
Adds a breakpoint at line
(and optionally column
) in the script with
the given canonical uri
.
Both line
and column
are 1-based. The uri
may be a String or a
Uri.
Implementation
Future<VMBreakpoint> addBreakpoint(uri, int line, {int column}) async {
if (uri is! String && uri is! Uri) {
throw new ArgumentError("Invalid uri '$uri', must be a Uri or a String.");
}
var params = {"scriptUri": uri.toString(), "line": line};
if (column != null) params["column"] = column;
try {
var response =
await _scope.sendRequest("addBreakpointWithScriptUri", params);
return newVMBreakpoint(_scope, response);
} on rpc.RpcException catch (error) {
// Error 102 indicates that the breakpoint couldn't be created.
if (error.code == 102) return null;
rethrow;
}
}
