Charts

Clip support for annotations

The Flutter Cartesian Charts’ annotation will be hidden by default when it exceeds the PlotArea or ChartArea. From this 2024 vol 1 release onward, we can clip the exceeding portions by specifying the ChartClipBehavior .clip property in the annotation.

Touch support for annotations

Interactions are now functional when embedding an interactive widget within an annotation in the Flutter Charts.

Cross-axis rendering improvements

In the previous versions, the plot area’s axis was placed beneath the series, which made it hard to see. However, in this release, we have improved this rendering behavior by ensuring the axis is always rendered on top of the series.

Enhancements in Funnel Series’ legends rendering

Based on the data source sequence, we’ve improved the rendering order of the legend items in the Funnel Series. Now, the legend items are rendered in the same order as the data source, usually from bottom to top, reflecting the rendering order of the funnel series.

Custom segment rendering

We’ve also added support for Circular, Funnel, and Pyramid Charts to enable custom rendering for the series. This allows for individual and collective customization of the segments.

Spark Charts

In the Flutter Spark Charts, we’ve included Theme support to customize the default styles of all Spark Charts.

PDF Library

The Flutter PDF Library provides support for the following user-friendly features:

Check box form field enhancements

Enables users to toggle the selection of grouped check box items within PDF documents. This feature provides users with enhanced management of their form fields, improving the user experience with PDF forms.

Digital signature enhancements

This feature enables asynchronous PDF signing through external integration. This improvement allows for more fluid workflows, as users can merge with third-party signing services effortlessly. With this upgrade, users gain greater adaptability, as they can now carry on with other activities while the signing operation occurs behind the scenes.

PDF Viewer

The new features included in the Flutter PDF Viewer are as follows:

Viewport rendering

When zoomed in closer, this function displays only the section of the PDF document that appears within the on-screen viewing area, disregarding the content beyond the visible frame.

Undo/redo support in form-filling

This feature enables users to undo and redo the data inputted in PDF forms, ensuring quick error correction without manually going through the entire form.
