Usage

Important: The methods return a NotionResponse. You can find how to use it in its documentation.

NotionClient class

You only have to create a new instance of the NotionClient class and all the API requests will be available as class methods.

NotionClient notion = NotionClient(token: 'YOUR SECRET TOKEN FROM INTEGRATIONS PAGE');

Individual classes

You can also use individual request group class like NotionPagesClient or NotionDatabasesClient. They are used like the main client but the methods are class methods instead of class properties methods.

Example

// With main class
NotionClient notion = NotionClient(token: 'YOUR_TOKEN');
notion.databases.fetchAll();

// With individual class
NotionDatabasesClient databases = NotionDatabasesClient(token: 'YOUR_TOKEN');
databases.fetchAll();

A few examples

A page created and filled using only this package:
https://jonathangomz.notion.site/notion_api-example-0893dd2cb38a413d90165cb810b3c019

To see code to create the page above or see more examples go here.

Append blocks children

// Create children instance:
Children children = Children.withBlocks([
  Heading(text: Text('Test')),
  Paragraph(texts: [
    Text('Lorem ipsum (A)'),
    Text('Lorem ipsum (B)',
        annotations: TextAnnotations(
          bold: true,
          underline: true,
          color: ColorsTypes.Orange,
        ))
  ])
]);

// Send the instance to Notion
notion.blocks.append(
  to: 'YOUR_BLOCK_ID',
  children: children,
);

Create a page

// Create a page instance
Page page = Page(
  parent: Parent.database(id: 'YOUR_DATABASE_ID'),
  title: Text('NotionClient (v1): Page test'),
);

// Send the instance to Notion.
notion.pages.create(page);

Errors

Some errors that I have encounter and still don't know how to solve because are errors that also occur on Postman are:

Create page with chidren

When the parent is a page the error is:

"body failed validation: body.properties.title.type should be an array, instead was `\"array\"`."

But when the parent is a database then the error is:

"body failed validation: body.parent.page_id should be defined, instead was `undefined`."

You can create the page first and then add the children as shown in the examples.

Contributions

Please help, I don't even know if what I'm doing is right.

Rules

Some rules to follow:

1. Please follow the dart convention format:
   1. Effective dart
   2. dart format
2. If you are adding a new function, please also add the documentation.
3. If you are adding a new parameters, please also add it to the current documentation.
4. (Optional) Run the tests to know that everything is working just fine (See how run the tests).
   • This is optional because sometimes the tests fail on GitHub actions so anyway I will check this on my computer.

Tests

To be able to run the tests you will have to have a .env file on the root directory with the next variables:

• TOKEN: The secret token.
• TEST_DATABASE_ID: The database id where you will be working on.
• TEST_PAGE_ID: Some page id inside the database specified above.
• TEST_BLOCK_ID: Some block id inside the page specified above.
• TEST_BLOCK_HEADING_ID: Some heading block id inside the page specified above.

Example:

The values are not valid of course.

TOKEN=secret_Oa24V8FbJ49JluJankVOQihyLiMXwqSQeeHuSFobQDW
TEST_DATABASE_ID=366da3d646bb458128071fdb2fbbf427
TEST_PAGE_ID=c3b53019-4470-443b-a141-95a3a1a44g60
TEST_BLOCK_ID=c8hac4bb32af48889228bf483d938e34
TEST_BLOCK_HEADING_ID=c8hac4bb32af48889228bf483d938e34

Next release

v1.2.1:

Release date: 02/Aug/2021

• Add constructors with only single text content with default style for:
  • Paragraph.text('some text here...')
  • ToDo.text('some text here...', checked: true)
  • Heading.text('some text here...', type: 2)
  • BulletedListItem.text('some text here...')
  • NumberedListItem.text('some text here...')
  • Toggle.text('some text here...', children: [])
• Add more constructors for Heading class:
  • one: Heading with type 1 by default.
  • two: Heading with type 2 by default.
  • three: Heading with type 3 by default.
• Add more constructors for Text class:
  • code: Text with code style by default.
  • italic: Text with italic style by default.
  • bold: Text with bold style by default.
  • [Opt] list: List of words separated by comma (by default).
    • Example: Text.list() will receive a list of Text and will be concatenated separated with comma by default. It may be unnecessary. Can help to make the code more readable.
  • [Opt] sep: Text separator.
    • Example: Text.sep(), by default, will insert " " in a list of Text instances, but it will be able to do more things that I don't know yet, hehe. It may be unnecessary. Can help to make the code more readable.
