FormulaBuilder typedef

FormulaBuilder = Widget Function(BuildContext context, String formula)

LaTeX formula rendering support

This provides basic formula rendering for Quill Delta embeds. For production use, consider using flutter_math_fork for full LaTeX support.

Supported Features (Basic)

• Superscript: x^2
• Subscript: x_1
• Fractions: \frac{a}{b}
• Greek letters: \alpha, \beta, etc.
• Common symbols: \sum, \int, \sqrt

Usage with Quill Delta

{
  "ops": [
    { "insert": { "formula": "E = mc^2" } }
  ]
}
