Additionally this adds a testcase for ```useLegacyStretchBehaviour``` Fixes #633 Closes https://github.com/facebook/yoga/pull/635 Differential Revision: D6408037 Pulled By: emilsjolander fbshipit-source-id: 377ab0308dd3a75a148a0af31ab5eb3ffb5b5d83 --- ReactCommon/yoga/yoga/Yoga.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/ReactCommon/yoga/yoga/Yoga.cpp b/ReactCommon/yoga/yoga/Yoga.cpp index 7345e055c0d08d..ba5fb183f62a1a 100644 --- a/ReactCommon/yoga/yoga/Yoga.cpp +++ b/ReactCommon/yoga/yoga/Yoga.cpp @@ -2123,6 +2123,7 @@ static void YGNodelayoutImpl(const YGNodeRef node, // If the main dimension size isn't known, it is computed based on // the line length, so there's no more space left to distribute. + bool sizeBasedOnContent = false; // If we don't measure with exact main dimension we want to ensure we don't violate min and max if (measureModeMainDim != YGMeasureModeExactly) { if (!YGFloatIsUndefined(minInnerMainDim) && sizeConsumedOnCurrentLine < minInnerMainDim) { @@ -2137,11 +2138,12 @@ static void YGNodelayoutImpl(const YGNodeRef node, // space we've used is all space we need.
