* **IMPORTANT** (by @imaNNeo) You can read more about this release and the history of fl_chart here in my [blog post](https://flutter4fun.com/fl-chart-1-0-0)

## 0.71.0
* **IMPROVEMENT** (by @MattiaPispisa) Add a new property called `BorderRadius tooltipBorderRadius` instead of (deprecated) `double tooltipRoundedRadius` in `BarTouchTooltipData`, `LineTouchTooltipData` and `ScatterTouchTooltipData` #1715
* **FEATURE** (by @frybitsinc) Add `children` property in our [RadarChartTitle](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/radar_chart.md#radarcharttitle), #1840

## 0.70.2
* **FEATURE** (by @imaNNeo) Add error range feature in our axis-based charts. You can set `xError` and `yError` in the [FlSpot](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#flspot) or `toYErrorRange` in [BarChartRodData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartroddata). Also we have `errorIndicatorData` property in our [LineChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#linechartdata), [BarChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartdata) and [ScatterChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#scatterchartdata) that is responsible to render the error bars. You can take a look at the [LineChartSample 13](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/line/line_chart_sample13.dart) and [BarChartSample 8](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/bar/bar_chart_sample8.dart) in our [sample app](https://app.flchart.dev), #1483 

## 0.70.1
* **FEATURE** (by @Peetee06) Add `panEnabled` and `scaleEnabled` properties in the TransformationController, #1818
* **FEATURE** (by @mitulagr2) Add `renderPriority` feature in our [ScatterSpot](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#scatterspot), #1545
* **FEATURE** (by @imaNNeo) Add `rotationQuarterTurns` property in our Axis-Based charts (such as [LineChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md), [BarChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md) and [ScatterChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md)). It allows you to rotate the chart 90 degrees (clockwise) in each turn. For example you can have Horizontal Bar Charts by setting `rotationQuarterTurns` to 1 (which rotates the chart 90 degrees clockwise). It works exactly like [RotatesBox](https://api.flutter.dev/flutter/widgets/RotatedBox-class.html) widget, #113
* **FEATURE** (by @soraef) Add `isMinValueAtCenter` property in the [RadarChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/radar_chart.md) to allow the user to set the minimum value at the center of the chart, #1351, #1442

* **BREAKING** (by @Peetee06) Fixed the equatable functionality in our BarChart. We hope it will not affect anything in our chart, but because the behaviour is changed, we marked it as a breaking change. (read more [here](https://github.com/imaNNeo/fl_chart/pull/1789#discussion_r1858371718))
* **BREAKING** (by @Peetee06) `BarChart` is not const anymore due to adding an assert to check if transformations are allowed depending on the `BarChartData.alignment` property (read more [here](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/migration_guides/0.70.0/MIGRATION_00_70_00.md))
* **IMPROVEMENT** (by @Peetee06) Upgrade to the new Flutter version ([3.27.0](https://medium.com/flutter/whats-new-in-flutter-3-27-28341129570c)), #1804

(Read our [Migration Guide](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/migration_guides/0.55.0/MIGRATION_00_55_00.md) to learn more about it)

## 0.51.0
* **FEATURE** (by @imaNNeo): Add `SideTitleWidget` to help you use it in [SideTitles.getTitlesWidget]. It's a wrapper around your widget. It keeps your provided `child` widget close to the chart. It has `angle` and `space` properties to handle margin and rotation. There is a `axisSide` property that you should fill, it has provided to you in the MetaData object. Check the below sample:
```dart
getTitlesWidget: (double value, TitleMeta meta) {
  return SideTitleWidget(
    axisSide: meta.axisSide,

* **BREAKING** Structure of `FlTitlesData`, `AxisTitles`, and `SideTitles` are changed. Because we are using a new system which allows you to pass any [Flutter Widget](https://docs.flutter.dev/development/ui/widgets) as a title instead of passing `string`, `textStyle`, `textAlign`, `rotation`, ... (Read our [Migration Guide](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/migration_guides/0.50.0/MIGRATION_00_50_00.md))
* **FEATURE** Now we can use any [Gradient](https://api.flutter.dev/flutter/dart-ui/Gradient-class.html) such as [LinearGradient](https://api.flutter.dev/flutter/painting/LinearGradient-class.html) and [RadialGradient](https://api.flutter.dev/flutter/painting/RadialGradient-class.html) everywhere we have gradient.
* **BUGFIX** Fix BarChart rods gradient problem, #703.
* **BREAKING** `colors` property renamed to `color` to keep only one solid color. And now we have a `gradient` field instead of `colorStops`, `gradientFrom` and `gradientTo` in following classes: [BarChartRodData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartroddata), [BackgroundBarChartRodData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#backgroundbarchartroddata), [BarAreaData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#BarAreaData), [BetweenBarsData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#betweenbarsdata), [LineChartBarData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#linechartbardata).

## 0.40.0
* **BUGFIX** Fixed pieChart `centerRadius = double.infinity` problem, #747.c
* **BREAKING** Charts touchCallback signature has changed to `(FlTouchEvent event, BaseTouchResponse? response)` which [FlTouchEvent](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#fltouchevent) determines which touch/pointer event happened (such as `FlTapUpEvent`, `FlPanUpdateEvent`, ...), and BaseTouchResponse gives us the chart response.
* **BREAKING** Chart touchResponse classes don't have `touchInput` and `clickHappened` properties anymore. Use [FlTouchEvent](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#fltouchevent) provided in the callback instead of `touchInput`. Check `event is FlTapUpEvent` to detect touch events instead of checking `clickHappened`;
* **IMPROVEMENT** Again we support `longPress` touch events. check [FlTouchEvent](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#fltouchevent) to see all kind of supported touch/pointer events (which can be `FlLongPressStart`, `FlLongPressMoveUpdate`, `FlLongPressEnd`, ...). Also you can check out [touch handling doc](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/handle_touches.md), #649.
* **IMPROVEMENT** Added `mouseCursorResolver` callback in touchData classes such as [LineTouchData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#linetouchdata-read-about-touch-handling) and [BarTouchData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#bartouchdata-read-about-touch-handling). You can change the [MouseCursor](https://api.flutter.dev/flutter/services/MouseCursor-class.html) based on the provided [FlTouchEvent](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#fltouchevent) and touchResponse using this callback. (We have used this feature in [PieChartSample2](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#sample-2-source-code))
* **BUGFIX** Fixed `ScatterChart` default touchHandling crash
* **BUGFIX** Fix text styles when updating the theme. Check this [theme-aware-sample](https://gist.github.com/imaNNeo/bf95e720621d799ab980a7a3287c56e2).

* **BREAKING** `textStyle` of [ScatterTooltipItem](https://github.com/imaNNeoFighT/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#ScatterTooltipItem) is now nullable and optional. `bottomMargin` is also optional (default is zero). So both are named parameters now.
* **IMPROVEMENT** We improved touch precision of `ScatterChart`.
* **BUGFIX** Fix overlapping last gridlines on border lines problem.
* **NEWS** Your donation **motivates** me to work more on the `fl_chart` and resolve more issues. Now you can [buy me a coffee](https://www.buymeacoffee.com/fl_chart)!

## 0.36.4
* **IMPROVEMENT** Added `borderSide` property in [BarChartRodData](https://github.com/imaNNeoFighT/fl_chart/blob/main/repo_files/documentations/bar_chart.md#BarChartRodData) and [BarChartRodStackItem](https://github.com/imaNNeoFighT/fl_chart/blob/main/repo_files/documentations/bar_chart.md#BarChartRodStackItem) to draw strokes around each bar and rod stack items, #714.
