Flutter developers building mobile, web, or desktop applications that require inline data trend visualizations, such as fitness trackers, financial dashboards, or analytics tools.

Beautiful sparkline charts for Flutter
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a minimal API dedicated solely to sparklines, avoiding the bloat of full charting libraries, as shown in the quick start example with just a few lines of Dart code.
Supports line gradients, fill gradients, and point styling for visual appeal, demonstrated in README examples with configurable colors and effects.
Simple widget setup with sensible defaults, allowing developers to embed sparklines quickly into Flutter apps without complex configuration.
Offers pointsMode options to show all, last, or no points, with customizable size and color, giving control over chart density as illustrated in the README.
Lacks built-in gestures for selecting data points, with 'gesture detector to select closest point to tap' marked as pending in the Todo list, limiting user engagement.
Cannot animate between sparklines or drawing animations, as 'animate between two sparklines' and 'animate drawing a single sparkline' are unchecked in the Todo, reducing dynamism.
Does not include axis labels, a feature listed in the Todo, making it unsuitable for standalone charts that require contextual data annotation.
