PromptTemplate.fromExamples constructor

PromptTemplate.fromExamples({ required List<String> examples, required String suffix, required Set<String> inputVariables, String exampleSeparator = '\n\n', String prefix = '', bool validateTemplate = true, })

Take examples in list format with prefix and suffix to create a prompt.

Intended to be used a a way to dynamically create a prompt from examples.

• examples list of examples to use in the prompt.
• suffix string to go after the list of examples. Should generally set up the user's input.
• inputVariables list list of variable names the final prompt template will expect.
• exampleSeparator the separator to use in between examples.
• prefix string that should go before any examples. Generally includes examples.
• validateTemplate whether to validate the template.

Implementation

factory PromptTemplate.fromExamples({
  required final List<String> examples,
  required final String suffix,
  required final Set<String> inputVariables,
  final String exampleSeparator = '\n\n',
  final String prefix = '',
  final bool validateTemplate = true,
}) {
  final template = [prefix, ...examples, suffix].join(exampleSeparator);
  final t = PromptTemplate(
    inputVariables: inputVariables,
    template: template,
  );
  if (validateTemplate) {
    t.validateTemplate();
  }
  return t;
}
