fl_echarts 0.3.0

ECharts for Flutter — Android, iOS, macOS, Web & Windows. No JS knowledge needed. Powered by an embedded WebView.

0.3.0

• Re-add Web support via a custom HtmlElementView iframe — no webview_flutter_web dependency, no addJavaScriptChannel limitation.
• Fix web rendering: use a Blob object URL instead of srcdoc to safely load the 1 MB ECharts bundle.
• Fix web: runJavaScript commands are delivered to the iframe via postMessage.
• Re-add Windows support via webview_windows.
• Fix widget lifecycle on web: force a setState after init() so the iframe enters the DOM before waiting for the ready message.
• Package now supports 5 platforms: Android, iOS, macOS, Web, Windows.

0.2.0

• BREAKING: Removed web support due to platform limitations.
• Improved error handling for unsupported platforms.
• Updated isSupported check to exclude web.

0.1.0

• Add macOS support (via webview_flutter).
• Fix critical bug: echarts.init received undefined chartDom; corrected to use the chart DOM element.
• Fix resizeChart() calling chart.resize() instead of echart.resize().
• Add didUpdateWidget — chart re-renders automatically when option changes; controller re-attaches on swap.
• Fix showLoading JS string interpolation vulnerability (now uses jsonEncode).
• Add timeout to waitForECharts polling loop to prevent infinite spin when asset fails.
• Replace deprecated withOpacity with withValues(alpha:).
• Relax SDK constraint from ^3.7.2 to ^3.0.0.
