Quick Start

RichTextState

Use RichTextEditor composable to create a rich text editor.

The RichTextEditor composable requires a RichTextState to manage the editor's state.

To create a RichTextState, use the rememberRichTextState function:

val state = rememberRichTextState()

RichTextEditor(
    state = state,
)

Styling Spans

To style spans, RichTextState provides toggleSpanStyle method:

// Toggle a span style.
richTextState.toggleSpanStyle(SpanStyle(fontWeight = FontWeight.Bold))

To get the current span style of the selection, use RichTextState.currentSpanStyle:

// Get the current span style.
val currentSpanStyle = richTextState.currentSpanStyle
val isBold = currentSpanStyle.fontWeight = FontWeight.Bold

Styling Paragraphs

To style paragraphs, RichTextState provides toggleParagraphStyle method:

// Toggle a paragraph style.
richTextState.toggleParagraphStyle(ParagraphStyle(textAlign = TextAlign.Center))

To get the current paragraph style of the selection, use RichTextState.currentParagraphStyle:

// Get the current paragraph style.
val currentParagraphStyle = richTextState.currentParagraphStyle
val isCentered = currentParagraphStyle.textAlign = TextAlign.Center

Add links

To add links, RichTextState provides addLink method:

// Add link after selection.
richTextState.addLink(
    text = "Compose Rich Editor",
    url = "https://github.com/MohamedRejeb/Compose-Rich-Editor"
)

To get if the current selection is a link, use RichTextState.isLink:

// Get if the current selection is a link.
val isLink = richTextState.isLink

Add Code Blocks

To add code blocks, RichTextState provides toggleCode method:

// Toggle code block.
richTextState.toggleCode()

To get if the current selection is a code block, use RichTextState.isCode:

// Get if the current selection is a code block.
val isCode = richTextState.isCode

Ordered and Unordered Lists

You can add ordered and unordered lists using RichTextState:

// Toggle ordered list.
richTextState.toggleOrderedList()

// Toggle unordered list.
richTextState.toggleUnorderedList()

You can get if the current selection is an ordered or unordered list, using RichTextState:

// Get if the current selection is an ordered list.
val isOrderedList = richTextState.isOrderedList

// Get if the current selection is an unordered list.
val isUnorderedList = richTextState.isUnorderedList

Customizing the rich text configuration

Some of the rich text editor's features can be customized, such as the color of the links and the code blocks.

richTextState.setConfig(
    linkColor = Color.Blue,
    linkTextDecoration = TextDecoration.Underline,
    codeColor = Color.Yellow,
    codeBackgroundColor = Color.Transparent,
    codeStrokeColor = Color.LightGray,
)

HTML import and export

To convert HTML to RichTextState, use RichTextState.setHtml method:

val html = "<p><b>Compose Rich Editor</b></p>"
richTextState.setHtml(html)

To convert RichTextState to HTML, use RichTextState.toHtml method:

val html = richTextState.toHtml()

Markdown import and export

To convert Markdown to RichTextState, use RichTextState.setMarkdown method:

val markdown = "**Compose** *Rich* Editor"
richTextState.setMarkdown(markdown)

To convert RichTextState to Markdown, use RichTextState.toMarkdown method:

val markdown = richTextState.toMarkdown()
