Incorrect parameters in the error handler for TextInput in documentation

[serikurazmaxambetov2]

Problem Description:

In the official documentation example for the TextInput widget in aiogram_dialog, the error handler is defined as follows:

async def error(
    message: Message,
    dialog_: Any,
    manager: DialogManager,
    error_: ValueError
):
    await message.answer("Age must be a number!")

However, this appears to use incorrect parameters. According to the expected behavior for the on_error handler in the TextInput widget, the correct parameters should include:

• widget instead of dialog_
• data for additional context.

Proposed Solution

async def error(
    message: Message,
    widget: Any,
    manager: DialogManager,
    data: dict
):
    await message.answer("Age must be a number!")

Additional Information:

This issue is based on the example provided in the documentation for the TextInput widget. If I have misunderstood how the parameters are intended to work, I would appreciate clarification.

P.S. This issue is related to documentation.
